Yep. I didn't know how to solve it...

Yes, right. That is supposed to workaround a problem on Gentoo where the
version number check is strict, but the libtool.m4 and ltmain.sh from
MPFR do not have the same version number.

Should that cause a problem? IIRC, both files are from libtool, and
the version of autoconf is not problem.

That's not an option.

For the records, Gentoo is the only distribution I am aware of that exhibits
the problem, but the fix is quite sane anyway.

The -i flag is not documented in my version (1.5.26 from Debian lenny).
  libtoolize -f -i
  libtoolize: unrecognized option `-i'

Yes they are. That can be changed, but I don't have the time for this. Also,
I don't have Gentoo, so can't reproduce anything. You're welcome to provide
a patch... ;-)
