AUR package (cpio-git) fails to upgrade

Hello together,

at the moment pamac tells me, that there is a update for the cpio-git package available.

I tried to update this package with pamac.
But the build process ends with this error:

*** error: gettext infrastructure mismatch: using a Makefile.in.in from gettext version 0.19 but the autoconf macros are from gettext version 0.20
make[2]: *** [Makefile:232: stamp-po] Fehler 1

What can I do to solve the problem?

Thank you!
