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.

Howdy,

I'd guess you should change the line to

\input mp-spec.mpii

and see if it works. 2010 is a long time ago and, with the support of LuaTeX by ConTeXt (mkiv) as well as the, historical, pdftex (mkii) things will undoubtedly have changed.

PS: this is definitely a guess!
 
Good Luck,
