- pull sources directly into pkgsrc - do not depend on namespace.h, <sys/cdefs.h> (de-__P()ify), or <err.h> - use libtool for better portability in shlib creation The resultant library is still ABI compatible with prior versions and should have the same shlib major version number. Thanks to Roland Illig <roland.illig@gmx.de> for help in getting this working properly on Solaris.
