Yes, the blastwave compiler is in my experience next to useless. I
build or use a custom build toolchain on Solaris when I use gcc for
that reason. If you build your own gcc make sure to also use the
latest binutils.
The problem you hit happens on some occasion when you link static
libraries which in case of pari is probably gmp. Pari seems to provide
two version of libpari in some occasions: one with a dynamic gmp and
one with a static gmp link in. I don't know why they do, I can
speculate for some reasons but overall that seems to be not the choice
I would make.
Once Solaris support is progressing for Sage I will explicitly mention
it in the release notes. I usually get each Sage release to build, but
it is not a trivial task.
Cheers,
Michael
