I have Mono working nicely on my FreeBSD-CURRENT installation, with one
minor issue: whenever mcs tries to build something using the -pkg flag,
it core dumps. Here's a screenlog of a minimal test case:
[(22:46:35) apeiron@prophecy ~] cat foo.cs
using Gtk;
class Foo
{
public static void Main()
{
int bar =3D 1 + 1;
}
}
[(22:46:40) apeiron@prophecy ~] mcs -pkg:gtk-sharp foo.cs
Segmentation fault (core dumped)

My guess is that mono (and / or its interactions with libpthread) has
difficulty with calling an external program, since that's what the -pkg
flag does. I'm not sure of what else I can provide other than the
boilerplate system information.

I found that mono had problems installing unless I added lt-mono. This
is on a machine using nVidia binary drivers, though I'd be glad to try
testing with unconstrained mapping of libpthread.so* to libpthread.so*
if anyone believes that it will yield more information. I'd provide a
full package listing, but I doubt that anyone wants 691 more lines from
me. :) And yes, that *is* with pkg_cutleaves.
