That is confusing that he found part of gmp, but not the library.  If
you do the following, replacing /opt/csw with /usr/local, then it still
does not make sense.  But at least, libgmp.so would look correct.

[asmoore at ra ~]$ nm -D /opt/csw/lib/sparcv9/libgmp.so.3.3.3 |grep
__gmpz_init 
[287]   |        118872|         128|FUNC |GLOB |0 |9      |__gmpz_init 
...

Both of the above lines should be on one line.

For some reason, I build mpfr and gmp with LD_OPTIONS containing
part of what I normally define in LDFLAGS, i.e., '-L /opt/csw/lib'.  So
you might try that.  On Solaris, LDFLAGS with '-L<lib directory>' is
normally for the compiler to search for libraries.  LD_OPTIONS is
normally the run-time library search path beyond the normal system
search path.  LD_OPTIONS is '-R<lib directory>:<lib directory>...'  See
man ld

For gmp and mpfr on sparcv9, I use:
LD_OPTIONS='-R/opt/csw/lib/sparcv9 -L/opt/csw/lib/sparcv9' ; export
LD_OPTIONS
Again on one line.  I use ksh or bash.

I will patch libmpfr 2.2.0 on www.blastwave.org very soon with the
2005.11.25 cumulative patch set.
