meld @3.18.0 fails to build because itstool failed with exit status 1

meld fails to build (on 10.12 and 10.13, at least) because of itstool:

​https://build.macports.org/builders/ports-10.12_x86_64-builder/builds/43466/steps/install-port/logs/stdio

msgfmt help/cs/cs.po -o build/help/cs/cs.mo
itstool -m build/help/cs/cs.mo -o build/help/cs help/C/command-line.page
error: command 'itstool' failed with exit status 1

meld builds fine on my 10.12 system, but I have lots of other ports installed. Could itstool or meld be missing a dependency?

Thanks for the catch!

With [10c47cd521eeb7c126191664f8330523224119a5/macports-ports], I built from a new Macports install successfully.

The builders don't seem to have picked it yet, so fingers crossed ;-)

[ryandesign (Ryan Carsten Schmidt)]

Yup, success! Thanks.

Didn't even occur to me that the problem might be that itstool wasn't there at all.
