Brr... I am sorry but I just don't understand what are you trying to do.
Install LibXML2, LibXSLT and OpenSSL (say using Fink) and do usual
./configure
make
make install
I just recompiled xmlsec 1.0.2 and everything seems to work except that
the libxslt version in fink is pretty old. I had to change configure
script to
downgrade minimum required libxslt version.
