[MonoDevelop] MIssing/invalid libgtkembedmoz.so?

[David Hovel]

My recently-built version of MonoDevelop gives "DLL not found" for
libgtkembedmoz.so.  I have the DLL on my machine, but it's not
in /usr/lib/mozilla (which I don't have) or /usr/lib/firefox (which I
do).

Where should I get this?  What do I tell MD to find it?

Thanks,
