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.
Taking a look
Note that maxima builds fine on the official builders: http://pkg.freebsd.org/FreeBSD:12:amd64/latest/All/maxima-5.43.0_1.txz
Can you please check your poudriere's DEFAULT_VERSIONS settings? It could be in any of the files listed in CUSTOMISATION / Create optional make.conf in man 8 poudriere.
I checked better and saw that I badly merged the maxima port in my poudriere ports tree, so that it had "USES= tk:85+" instead of "USES=tk" as I had instead wrongly stated in my first message (it was another ports tree that had "USES=tk"). Then it was my fault and everything works fine. I am sorry for the mistake. Thanks anyway for your time.
Thanks for double checking.
