-------------------------------------+--------------------------------------
 bison was updated to 2.4 but bison 2.4 is incompatible with some software
 that requires bison, like [http://groups.google.com/group/pure-
 lang/t/60593b93dc8fcf63 pure-devel] and
 [http://lists.macosforge.org/pipermail/macports-
 dev/2008-November/006328.html libidl]. We should make a new port bison23
 based off the 2.3_2 version of the bison port and modify it to install
 files in a new place, so both can be installed at the same time.
