Comment:

 Replying to [ticket:60130 JDLH]:

 > :info:configure checking for XML::Parser... configure: error:
 XML::Parser perl module is required for intltool

 This appears to be a new problem in 1.5.1. I am able to reproduce the
 problem in 1.5.1 (by installing perl5 +perl5_26), but not in 1.5.0.

 workaround.

 Certainly, but you should not need to do that.

 > However, #58012 was fixed by including code in the Portfile to
 "reconfigure with our intltool.m4 using upstream autogen.sh" (see
 changeset:0fe1ca9a3b956f9e0e3d61c233ae3b868022ccfb/macports-ports). That
 code is still in the Portfile, yet the regression occurred.

 libmypaint from 1.5.0 to 1.5.1. See
 changeset:438b73a9b9b1433e9a7661d279fb73643ad53254/macports-ports.

 In 1.5.1, they started bundling a copy of intltool.m4, thus defeating the
 fact that we have an improved intltool.m4 in our intltool port. So we
 either need to patch the bundled intltool.m4 or else maybe just delete it
 so that the one from the intltool port gets used.
