Building Perl port

To build with Perl support you need to go

make perl

at the top level. This should build everything correctly. The only problem is if you have a Solaris or *BSD box. If so you need to compile with -fpic or -fPIC depending on your compiler. This needs to go into the top level CFLAGS line. In addition, in the out-of-the box perl distribution for solaris they built it with a different compiler to the one it comes with (idiots!), so the perl generated makefile has the wrong -fpic option. You need to edit that by hand.
