Well, your post makes no other reference to -lxosd ... but it means:
links with the library libxosd.[so|a]

But if the session you pasted is accurate, you problem is that you are
trying to execute a library, and that makes makes no sense.

Where you typed primes.so in the text above, do instead
# python
>>> load primes

What is happening is that you are compiling an extension to the python
library (primes.so).  This is a C library.  It cannot be executed (what
you in effect tried to do by typing primes.so).  But it can be loaded
into python.

Or I'm very confused.  Definitely one or the other.
