#60130: libmypaint @1.5.1_0: upgrade fails on configure with "error: XML::Parser
perl module is required for intltool" (regression)

--------------------+------------------------
 When I do `port upgrade libmypaint` to bring libmypaint @1.5.0_0 to
 @1.5.1_0, the configuration fails in exactly the same way as #58012:
 {{{

 I'm attaching …`libmypaint/main.log` and
 …`libmypaint/work/libmypaint-1.5.1/config.log`, but the punchline appears
 to be this, in `main.log`:
 {{{
 :info:configure checking for perl >= 5.8.1... 5.26.3
 :info:configure checking for XML::Parser... configure: error: XML::Parser
 perl module is required for intltool
 }}}

 Just as in #58012, tweaking the Perl5 variant is an effective workaround.
 {{{
 % sudo port upgrade --enforce-variants perl5 -perl5_26 +perl5_28
 }}}

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

 The Portfile was changed on 24 Feb 2020 (just yesterday) to upgrade
 libmypaint from 1.5.0 to 1.5.1. SEe https://github.com/macports/macports-
 ports/commit/438b73a9b9b1433e9a7661d279fb73643ad53254#diff-
