I was compiling libtool at Archlinux with 'srcpac -Sb libtool' when it happened: some tests failed and I got the message "send it to them".
It's my second trouble with libtool today; as I was compiling another package (I don't remember which... I am recompiling my entire system!) that requires libtool, maybe (dunno, I'm a beginner) it is useful: http://gcc.gnu.org/ml/gcc-patches/2008-03/msg00110.html (curiously, my Autoconf is 2.67, not 2.62...)
Sorry for the bad english, and thank you very much by GNU developing ;)
