Yes, I am also running on OpenSolaris 2010.03 in order to get as many
indications as possible. OpenIndiana works better, but fails on four
tests in libunistring-0.9.3. One error is avoided using

  ./configure SHELL=/usr/gnu/bin/sh      (or /usr/bin/bash)

since

  /usr/bin/sh --> /usr/bin/i86/ksh86

on OpenIndiana, as well as OpenSolaris, fails to use the idiom

    ${1+"$@"}

as POSIX and GNU expect when the sole argument $1='' is empty.
This is crucial in one libtool scripted test, whence this one
test case fails with the naive configuration.

Judging from the printout, you have omitted every command line switch
to "./configure". No wonder you have troubles reaching the set goal!

On my OpenIndiana system, gnutls-3.0.22 works fine with

  ./configure CPPFLAGS="-I/usr/include/gmp -I/usr/include/idn" \
       --with-libnettle-prefix=/export/home/mats/roen
 
Remember LD_LIBRARY_PATH in case of need for all tests. As we have learned
already, libnettle and also Simonsson's work are picky about the location
of <gmp.h> and <idna.h>, so they need manual help in CPPFLAGS.

The tests are passed except some stalled network communication where
gnutls-srv and gnutls-cli are waiting for each other. I have not got
around to debug those.

Best regards,
