Actually, I ran into the same problem a few weeks ago. It happened after upgrading mono 2.2 to 2.4 I had been googling for similar cases a well, and tried similar things like you.
I also installed MonoDevelop, which was suggested as a fix by someone, but that didn't solve it for me. At this moment it IS working, and I'm not sure how I got there. These are the things that might have caused it to start working again: - Numerous uninstalls and reinstalls of both mono 2.2 and 2.4 - Updated monobjc from 2.0.324 to 2.0.342 - made sure I was using the most recent NAnt.monobjc.dll - I also got around to update my Mac with the latest updates: I'm not at the most recent MacOS v10.5.6 Build 9G55 It must have been one of these actions or even a combination that has cured this weird behavior of nant Good luck and let us know how it goes. I know it's frustrating. -----Original Message----- From: Ron Grove [mailto:ron.gr...@me.com] Sent: vrijdag 24 april 2009 1:16 To: users@lists.monobjc.net Subject: Re: [us...@lists.monobjc.net] Problem building samples Interestingly I can run and run the command /Library/Frameworks/Mono.framework/Commands/pkg-config --list-all and mono is in the list it outputs.
