Early on in the alpha cycle there was an issue with Solaris/gcc (the -fPIC 
option to gcc was not being used, leading to errors when linking), but this
has been fixed for some time. 2.1 and its modules compile happily on my Solaris
boxes (Solaris 8, gcc 2.95.2). Have you got the final release of 2.1?
"configure.in" should have around line 637:

if test -z "$CCSHARED"
then
        case $ac_sys_system/$ac_sys_release in
        SunOS*) if test "$GCC" = yes;
                then CCSHARED="-fPIC";
                fi;;

and output from "make" should include lines like the following when building
the shared extensions:

building 'struct' extension
creating build
creating build/temp.solaris-2.8-sun4u-2.1
gcc -g -O2 -Wall -Wstrict-prototypes -fPIC -I. -I/export/home/mark/src/python/CV
S/python/dist/src/./Include -I/usr/local/include -IInclude/ -c /export/home/mark
/src/python/CVS/python/dist/src/Modules/structmodule.c -o build/temp.solaris-2.8
-sun4u-2.1/structmodule.o
creating build/lib.solaris-2.8-sun4u-2.1
gcc -shared build/temp.solaris-2.8-sun4u-2.1/structmodule.o -L/usr/local/lib -o 
build/lib.solaris-2.8-sun4u-2.1/struct.so

The core part of python is compiled by lines like:

gcc -c -g -O2 -Wall -Wstrict-prototypes -I. -I./Include -DHAVE_CONFIG_H  -o Modu
les/python.o Modules/python.c

The library is built like so:

ar cr libpython2.1.a Parser/acceler.o etc, etc, etc

and Python itself linked like so:

gcc   -o python \
                Modules/python.o \
                libpython2.1.a -lpthread -lsocket -lnsl -ldl  -lthread   -lm  

Hope this helps...
