Configure lied.  We updated the compiler in such a way that required
boostraping the new change and neglected to update the configre script to
detect incompatible versions.  I'll try to get that fixed.

The easiest solution is to delete and re-unpack your build tree, and repeat
your actions again except without mmc in your path.

One thing I like to do is use "stow" to manage my /usr/local filesystem.  if
I install things with --prefix /usr/local/stow/mercury-*VERSION* then from
within /usr/local/stow I run the "stow mercury-*VERSION*" command and it
creates symlinks to that version of Mercury.  This way I can have many
Mercurys installed at once, and uninstallation is as simple as stow -D
mercury-*VERSION*; rm -rf mercury-*VERSION*  This isn't required, I just
think it's a good idea.
