It seems that the file mp-spec.mp has been replaced by two files, mp-spec.mpii and mp-spec.mpiv, the former to be used by ConTeXt-mII and the latter by ConTeXt-mIV.  I would suggest to change the program which calls mp-spec.mp and make it call mp-spec.mpii instead. It this program is part of the MetaPost core files, it may be necessary to warn the MetaPost maintainers of this bug.
