I'm using Gentoo's portage (command: emerge) to install several packages on my brand new Linode, but it halts on lcms-1.13, like this:

*** Gentoo sanity check failed! ***
*** libtool.m4 and ltmain.sh have a version mismatch! ***
*** (libtool.m4 = 1.5.16, ltmain.sh = 1.5) ***

Please run:

  libtoolize --copy --force

if appropriate, please contact the maintainer of this
package (or your distribution) for help.


!!! Please attach the config.log to your bug report:
!!! /var/tmp/portage/lcms-1.13/work/lcms-1.13/config.log

I've already tried this, ie. going directly to /var/tmp/portage/lcms-1.13/work/lcms-1.13/ and running the libtoolize command above. After doing so, I tried the usual suspects (./configure, followed by make and make install), no errors appearing. After that, I tried emerging mod_php (or just php, for that matter), and it still tries to emerge lcms-1.13 among the packages (I'm always using the -av options to get a full overview of what's being installed).

Now what? Any ideas?

Also, at the start of this emerge process, I notice this:

emerge --oneshot libtools fixed it for me (or at the least the part that hung me up before).

Didn't seem to help much (no change). Do I need to unmerge libtool first?

UPDATE: Out of "desperation", I now deleted the files for lcms from /usr/tmp/portage and from /usr/portage/distfiles, forcing it to re-download the source code file.

It's successfully compiling now. No errors so far. Odd indeed.

Whenever you hit what appears to be a bug on Gentoo:

First step: visit http://bugs.gentoo.org

Second step: do a search. I used: ALL lcms libtool

It returned a list of three bugs. This looks to be your bug for lcms 1.13 and libtool:

http://bugs.gentoo.org/show_bug.cgi?id=74442

It's fixed in 1.13-r1... or you can apply a patch for 1.13 and rebuild the digest (easy). I see you've found a different workaround.
