mono-addins-0.3.1 port fails with Error 1

[John Murphy]

I'm trying to get the software for an open source software defined
radio project, which is written in c#, working on FreeBSD. I've
applied to join the BSD# mailing list, but have not received a
response as yet.

I need mono-develop (it's actually merged into the ports framework
after using the mono-merge script), but it depends on mono-addins
which fails to install with the output below. I was wondering if
anyone here has any suggestions.

I'm running 6.3-release, all installed ports are up to date, as is
the ports tree itself.
