Building gdmodule-0.23 under Python2.1.1

[Chris Gonnerman]

(Note:  I am the poor sucker who maintains this package now.)

Your problem looks like a linker error.  Specifically, you are linking
gdmodule.so with libgd.a; is it PIC (Position Independent Code) on Solaris
as it is under SuSE Linux (where I do my development work)?  The command 
you show to compile gd object modules does not include -fPIC.

The key message seems to be:

> ImportError: ld.so.1: python: fatal: relocation error: file
> ./gdmodule.so: symbol gdImageCreateFromJpeg: referenced symbol not
> found

In particular, "relocation error" sounds a lot like a PIC/non-PIC error.

Try adding -fPIC to the gcc command (and recompile ALL the gd source files
and rebuild the library) and see if that helps.
