Doesn't look like it, so the portgroup is unnecessary.

The elements of compiler.blacklist are treated as patterns for "string match", which closely resemble shell globs.


So this matches (and thus blacklists) GCC 4.0, 4.1, and 4.2:

    compiler.blacklist {*gcc-4.[0-2]}

Right. Asterisks and hyphens don't have to be quoted, but brackets do.

> Blacklisting gcc 4.3 and greater is probably never needed since there is no circumstance in which MacPorts would have chosen that compiler anyway.

I've done this before in the name of thoroughness, but it's generally not necessary.
