Guix distributes quilt version 0.66, there is a version 0.67 that quilt released as a tarball in 2022 but this version still has the bug in its test suite as it relates to the latest grep.
I just tried, at the time of writing the HEAD (as cloned) of the git repo of quilt successfully goes through the check target of its Makefile. I got it through: git clone https://git.savannah.nongnu.org/git/quilt.git And I completed the make check with their commit: c1ce964f3e9312100a60f03c1e1fdd601e1911f2 I have a dire need for quilt to build in guix because I use netcat-openbsd a lot. For practical reasons, it would be much better (for me) if a fix could hit the master branch quickly. Buf if not... well, I suppose this can be worked around with a special quilt and a special netcat-openbsd package.
