On OpenServer, I usually just build with the SONAME being a full path name.
I am attaching a patch to the libtool 2.4.6 generated during
a libssh2-1.8.0 build.
Once all testing is complete, I do
......
rm src/libssh2.la
SCOABSPATH=1 ; export SCOABSPATH
gmake 2>&1 | tee x.log
......
then package.
Note: the last hunk is to address a regression introduced in 2.4.6
with the freebsd reorg.
