I meant to blog this when rtyler and I found it the other night. He come into #Mono complaining that NAnt - delivered with Mono - wasn’t working at ALL on OS X. We spent a lot of time looking around and it came down to pkg-config.

The pkg-config shipped with mono isn’t the one being run by default. So it can’t find the .pc files in a relative path. It took a bit longer than it should’ve to find the solution, partly because I wasn’t overly verbose about the man page referencing PKG_CONFIG_PATH and I wasn’t setting it properly.

Anywho, it’s all over on his blog here.
