I'm maintainer both for maxima and wxmaxima, and I'm building maxima with poudriere as a dependency to test the new version of wxmaxima. The build fails with the message "Minimum tcltk version 85+ is meaningless", although I did not ask for any specific version in maxima's Makefile (it only has USES= tk).
However everything is fine if I try to build maxima from ports.
I guess this is related to last commit on Mk/Uses/tcl.mk, revision 504026.
I add that this seems to happen only in a 11.2-RELEASE jail: the 12.0-RELEASE jail is fine, as my system, which is 12-STABLE.
