Hi,
  when building on Solaris 2.6 with gcc I get the following error:

Let me add that I see -fPIC in the top-level Makefile but do not know
why -static is not in the same variable as well. Anyway, it is not
a shared library problem I think as I already recompiled my bzip2,
openssl and ncurses libs with "-shared -fpic". ;-)
