Gpredict fails at configure when trying to upgrade

[dershow]

I have gpredict 2.2.1_1 installed, and I just tried to upgrade to 2.2.1_2. It fails to configure. I've attached my log.

[Schamschula (Marius Schamschula)]

Very strange. I normally test build using a High Sierra machine. I just installed predict on a Mojave machine, w/o any problems.

I noticed that your configure log has Perl 5.26 rather than Perl 5.28. The Portfile specifies Perl 5.28.

I hadn't installed Perl directly, so it is there due to a dependency. I just checked what perl I have installed and I see this:

  perl5 @5.26.1_0+perl5_26 (active)
  perl5.26 @5.26.3_2 (active)
  perl5.28 @5.28.2_0 (active)

So, it looks like gpredict is not finding the correct version, but it is there.

I have an idea what to do. I'll test it later today.

I just ran into the same issue on another machine. Careful rereading of the error:

error: XML::Parser perl module is required for intltool

port info libtool shows that it now is built against Perl 5.28.

Your only option is to upgrade perl5:

sudo port install perl5 +perl5_28

Replying to Schamschula:

No, this is a bug in the configure script. It doesn't need to care which version of perl intltool is using internally. We submitted a patch to intltool upstream years ago, but nobody has ever reacted to the report, so configure scripts generated by upstream projects remain affected.

If you regenerate the configure script with the intltool port installed, it will use the patched intltool.m4 and the problem will go away. (It looks like gpredict may not need the perl5 portgroup or any perl dependencies at all?)
