Inform the linker where to automatically look for libraries. For
instance, if Beast is going to be installed into /usr/local, then
the following would be passed to the linker via gcc:

-Wl,-R/usr/local/lib

This will make the linker search for libaries in /usr/local/lib
as well as the standard locations. This is the ELF standard way
of finding libraries in non-default locations. Linux extends this
by having /etc/ld.so.conf list extra library locations, (the BSD
developers consider this a kludge).

I cannot speak for FreeBSD, but /usr/include/soundcard.h on NetBSD
describes an OSS compatible layer on top of the native audio
driver.

I am currently away from home, but looking forawrd to testing the
new release on NetBSD. I will attempt to do this on a NetBSD
machine in the first week of January, and if successfull will
post patches for Beast's pkgsrc/wip entry to the maintainer.
