it would see that the new libtool-1.5.10 ebuild has a bunch of maintainers
with broken ebuilds and not knowing what's going on
here's a quick 'how to fix your broken ebuilds' guide ... but first, some
background on WHY your ebuilds are broken, and libtool is, in fact, the sane
one in this yankee doodle circus
people, when fixing packages, often patch the source files rather than the
generated ones (fix configure.{in,ac} instead of configure, etc...) and then
run the autotools programs (aclocal/autoconf/automake/etc...) to rebuild
configure/etc... the problem is that these steps update only half of the
libtool files (libtool.m4). the other bundled libtool files (ltmain.sh /
libtool) are still the same old crusty versions. so when you run ./configure
after running `autoconf`, the configure script bails with this:
*** Gentoo sanity check failed! ***
*** libtool.m4 and ltmain.sh have a version mismatch! ***
*** (libtool.m4 = 1.5.10, ltmain.sh = 1.5.2) ***
these files (libool.m4, ltmain.sh, libtool) all must be from the same
version ... other wise, internal variables will be named differently and
weird crap can happen (the best example of this is libraries suddenly losing
their '.so' extensions). previous libtool ebuilds would try to hack around
the whole process by running `sed` on libtool to rename internal
variables ... well base-system decided we're not pulling that crap
anymore :). there's no easy way anymore to figure out what the new variable
needs to be in order to match up with the older version.
so now we've made it the maintainers' problem to fix their broken ebuilds (oh
the humanity!)
where's the friggin HOWTO i promised you may be asking !? it's quite simple
really ... if you run `aclocal` or `autoreconf` or any of that crap, stick a
`libtoolize --copy --force || die` in the mix. that will update the
ltmain.sh / libtool files while the aclocal/autoreconf/blahblah will update
the libtool.m4
if you want more references, use google or something
