Only Bytecode, No .py Files

Is that really a problem? AFAIK there are many failing open() calls on 
the start of every program.

E.g.

open("/lib/bash/4.1/tls/i686/sse2/libncurses.so.5", O_RDONLY) = -1 
ENOENT (No such file or directory)
stat64("/lib/bash/4.1/tls/i686/sse2", 0xbfd3a350) = -1 ENOENT (No such 
file or directory)
open("/lib/bash/4.1/tls/i686/libncurses.so.5", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/tls/i686", 0xbfd3a350) = -1 ENOENT (No such file 
or directory)
open("/lib/bash/4.1/tls/sse2/libncurses.so.5", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/tls/sse2", 0xbfd3a350) = -1 ENOENT (No such file 
or directory)
open("/lib/bash/4.1/tls/libncurses.so.5", O_RDONLY) = -1 ENOENT (No such 
file or directory)
stat64("/lib/bash/4.1/tls", 0xbfd3a350) = -1 ENOENT (No such file or 
directory)
open("/lib/bash/4.1/i686/sse2/libncurses.so.5", O_RDONLY) = -1 ENOENT 
(No such file or directory)
stat64("/lib/bash/4.1/i686/sse2", 0xbfd3a350) = -1 ENOENT (No such file 
or directory)
open("/lib/bash/4.1/i686/libncurses.so.5", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/i686", 0xbfd3a350) = -1 ENOENT (No such file or 
directory)
open("/lib/bash/4.1/sse2/libncurses.so.5", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/sse2", 0xbfd3a350) = -1 ENOENT (No such file or 
directory)
open("/lib/bash/4.1/libncurses.so.5", O_RDONLY) = -1 ENOENT (No such 
file or directory)
stat64("/lib/bash/4.1", 0xbfd3a350)     = -1 ENOENT (No such file or 
directory)
open("/lib/libncurses.so.5", O_RDONLY)  = 3

is a part of what happens if I start the MySQL client,

Even starting the bash results in

open("/lib/bash/4.1/tls/i686/sse2/libreadline.so.6", O_RDONLY) = -1 
ENOENT (No such file or directory)
stat64("/lib/bash/4.1/tls/i686/sse2", 0xbfe0c4d0) = -1 ENOENT (No such 
file or directory)
open("/lib/bash/4.1/tls/i686/libreadline.so.6", O_RDONLY) = -1 ENOENT 
(No such file or directory)
stat64("/lib/bash/4.1/tls/i686", 0xbfe0c4d0) = -1 ENOENT (No such file 
or directory)
open("/lib/bash/4.1/tls/sse2/libreadline.so.6", O_RDONLY) = -1 ENOENT 
(No such file or directory)
stat64("/lib/bash/4.1/tls/sse2", 0xbfe0c4d0) = -1 ENOENT (No such file 
or directory)
open("/lib/bash/4.1/tls/libreadline.so.6", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/tls", 0xbfe0c4d0) = -1 ENOENT (No such file or 
directory)
open("/lib/bash/4.1/i686/sse2/libreadline.so.6", O_RDONLY) = -1 ENOENT 
(No such file or directory)
stat64("/lib/bash/4.1/i686/sse2", 0xbfe0c4d0) = -1 ENOENT (No such file 
or directory)
open("/lib/bash/4.1/i686/libreadline.so.6", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/i686", 0xbfe0c4d0) = -1 ENOENT (No such file or 
directory)
open("/lib/bash/4.1/sse2/libreadline.so.6", O_RDONLY) = -1 ENOENT (No 
such file or directory)
stat64("/lib/bash/4.1/sse2", 0xbfe0c4d0) = -1 ENOENT (No such file or 
directory)
open("/lib/bash/4.1/libreadline.so.6", O_RDONLY) = -1 ENOENT (No such 
file or directory)
stat64("/lib/bash/4.1", 0xbfe0c4d0)     = -1 ENOENT (No such file or 
directory)
open("/etc/ld.so.cache", O_RDONLY)      = 3

So can it really be such a huge problem?
