Making and Installing Mono 0.30.1 on FreeBSD 5.1

Mon Mar 8 07:32:22 PST 2004

When I try to make and/or install mono 0.30.1 on my FreeBSD v. 5.1, I get 
the following error:

mono-0.30.1 is marked as broken: Unknown component pkgconfig.

What is going on here? Is there a way that I can get it to work? I can get 
mono 0.24 working just fine. However, I need to have a more recent version 
of mono running on my system as I would like to do a port of mod_mono onto 
FreeBSD, and the available sources are only compatible with more recent 
versions on mono.
