Spread uses autoconf now. So, it should be fixable with little effort.
Some of the key points to note:
Solaris cc uses -KPIC -DPIC instead of -fPIC to generate point
invariant code suitable for building shared objects and libraries.
Also, if you are running on a specific architecture and want to compile
for that you can add things like:
-xtarget=ultra -xarch=v9 -xcode=pic32
As for building shared libraries. Spread doesn't use libtool -- just
because I don't like it and I am the one who wrote the autoconf stuff.
If someone were to add libtool support into Spread and not break
anything, I'd wager the patch would be accepted.
Instead of "gcc -shared" to build the shared libraries, try: "ld -z
text -G" as the shared link command.

tspread is for threaded programs. It requires pthread mutexes for
concurrent mailbox access in multiple threads. If you use Spread in a
non-threaded fashion, link against -lspread, otherwise compile with the
-D_REENTRANT flag and link with -ltspread
