configure says: checking i686-pc-linux-gnu-gcc version... 1.0.1 which results in an error later. Seems to come from /stepmake/aclocal.m4:31. The following check (gcc --version || gcc -V) 2>&1 | grep '[0-9]\.[0-9]' | head -n 1 | sed -e 's/.*[^-.0-9]\([0-9][0-9]*\.[0-9][.0-9]*\).*/\1/' gives 1.0.1 on my system, where gcc --version prints: gcc (GCC) 4.1.2 (Gentoo 4.1.2 p1.0.1) Reproducible: Always Steps to Reproduce: emerge lilypond
Please use a 2.10.* version. I'm sorry, but policy prevents me from removing these obsolete versions while a new version is not yet marked stable, which cannot be done until guile-1.8* and a recent fontforge have been marked stable, both of which cause incompatibilities for other packages (see bug 182995).
