The DEPEND on wget or curl is unnecessary unless maintainer-mode is enabled. For 0.9.2 (at least) the removal of .gitignore files in unnecessary, as none are installed, except in the skeletonmm.tar.gz file that is installed to /usr/share/doc/mm-common. However, that appears to be intentional, as they are explicitly mentioned in Makefile.am. Additionally, docdir is not set during configure, so the skeletonmm tarball ends up outside /usr/share/doc/${PF}. Attaching a new 0.9.2 ebuild that fixes these problems.

Created attachment 247642 [details] mm-common live ebuild Additional live ebuild for mm-common. This does DEPEND on wget or curl as one of the two is required when building from git.
