dev-util/mcvs is three versions behind (1.0.10 instead of 1.0.13). At the time of writing this bug report, the only change to the ebuild's contents is to set DEB_PV=2 (instead of =3), this depends on what's available at http://ftp.debian.org/debian/pool/main/m/mcvs/ Obviously, the current file from that site should be also made available through Gentoo's distfiles repository (as done in the older ebuild), since they don't offer old versions.
Created attachment 32854 [details] mcvs-1.0.13 ebuild New ebuild for mcvs-1.0.13 containing user specified changes. Also had to fix the doman line to point to correct man page.
committed. had to patch the source, since it does not build with clisp-2.33.1 out of the box. thanks for the report.
Hmm, that's strange, I also have clisp-2.33.1 (which was freshly installed as a dep for mcvs), and I did not need any patch. But the real question is: Does this package need the ~x86 keyword? I don't know Gentoo's policy, but this program seems to be really stable, and there's no separate version marked as stable anyhow.
Is it possible your mcvs was linked with clisp-2.33? Looking in mcvs's source, it tries to make a real number out of clisp's version number at read time to form a conditional compilation feature. It will fail for a clisp version number with two periods in it (eg. 2.33.1). Since I didn't encounter any problems when testing mcvs and you say that it is stable, I will mark the ebuild as stable now.
Strange. I did compile mcvs with clisp-2.33.1 (I did not have it installed before) without any problems. But that's not important as long as your trivial patch works for everyone, which it really should.
