And while you are at it... You have not compiled python itself as PIC
code. No, gcc -shared *doesn't* work in Solaris unless you are using GNU
Binutils instead of the native linker and assembler, something *not
recommended at all*. Solaris' linker can't bild a dynamic loading
library/module using object code compiled in position dependent mode.

This means, that you need to have all external libraries compiled with
the -fPIC flag, even if they are static. Ahh! And make sure that you
give the linker the actual library paths you use with an -R flag, else
the dynamic loader won't find them and you'll have to use an explicit
LD_LIBRARY_PATH environment variable for each invocation invocation of
the internpreter.
