Build of Mono 1.2.3.1 fails if an older version of Mono is installed in /Library/Frameworks and /usr/bin

[frank.mcpherson@…]

When trying to build Mono via sudo port install mono, I get an error which I've attached below. I believe this error is related to having an older (1.0.0.0) version of Mono installed via an installer package in /Library/Frameworks, with links to the executables from /usr/bin.

Once I removed this old version of Mono from /usr/bin and /Library/Frameworks, the macports mono build seems to be proceeding. However, the Mono build should specify Macports versions of the tools, not pick them up from my ${PATH}.
