When trying to update clamav compilation fails while running autoconf: * Running aclocal -I m4 -I m4 ... [ ok ] * Running libtoolize --copy --force --automake ... [ ok ] * Running aclocal -I m4 -I m4 ... [ ok ] * Running autoconf ... [ !! ] * Failed Running autoconf ! Contents of autoconf-${pid}.out: ***** autoconf ***** ***** autoconf configure.in:325: error: possibly undefined macro: AC_MSG_WARN If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. Reproducible: Always Steps to Reproduce: 1. emerge --depclean --with-bdeps=n (pkgconfig removed if it was still installed) 2. emerge --update clamav Actual Results: Compilation failure When pkgconfig is installed emerging clamav works fine. So please add pkgconfig as build-dep to clamav.
Fixed in CVS. Thanks for reporting!
