To build MySQLdb, you might have to change some paths in setup.py, then do a
"python setup.py build". The files to install will then be in a directory named
not entirely unlike "build/lib.linux-i686-2.1". This directory is normally
copied to your site-packages dir. A simple way to use it on your provider is to
copy all of it into your cgi-bin (the py[c] files, the binary extension module
and the MySQLdb directory in it).

Better look into the MySQLdb docs, but here's a simple one:
con = MySQLdb.connect( user = "me", password = "verysecret", db = "mydb",\
host = "dbcluster" )
cursor = con.cursor()
cursor.execute( "select hello from world" )

No need to change any files *after* you compiled it. The dynamic loader must
find the libmysqlclient library, or you'll have a problem. If this should
really happen, you can perhaps link the Python extension module statically.
You'll notice that this is the case when "import _mysql" produces something
ImportError: libmysqlclient.so.10: cannot load shared object file: No such file
Hopefully, the standard way of setting "#!/usr/bin/env python" works as first
line of your scripts. If not, you'll have to put the full path to the
interpreter there ("#!/usr/local/bin/python" or whatever ...).
