Hello 

thank you very much Hubert for your report: errors like the one you
found (packages build failures) are bugs, next time please report them
to bug-guix@gnu.org; better to close a non-bug than to miss an actual
one ;-)

As you can see I've now filed a new bug: bug#63551

Thank you also to Vagrant and Denis for the heads up, please submit
further comments or patches to 63551@debbugs.gnu.org

Please do not wait for an official upstream "release" (git tag,
actually) for cpp-mustache, I guess upstream just forgot to tag it: Guix
is full of "not officially" released or properly tagged packages,
sources are often taken from carefully selected git commits (I've
recently proposed a patch for dia, that is in a very similar situation)

Since commit 4ed8c0b is setting version to 5.0.0 and that version works
(does it?), I'd go for an "update to 5.0.0" patch

My two cents.

[...]

Happy hacking! Gio'
