... because it was apparently recently upgraded to libtool-2.4.3. Here's the error from the log:
cd: /home/buildslave27/slave27/svn-trunk-nightly/uploads/roll/prefix/bin/../share/libtool/config: No such file or directory This is because, in the latest version of libtool, config.guess is no longer in .../share/libtool/config but in .../share/libtool/build-aux. I don't know if this can be changed at build time; in any case, our autogen.sh looks at the LIBTOOL_CONFIG environtment variable to find that path (and, heh, I just recently had to fix that bit of autogen.sh). Whoever is maintaining the nightly builder, please set LIBTOOL_CONFIG to point to the build-aux directory. -- Brane
