When attempting to compile gtk-rep (as part of Sawfish), I get the following error: libtool: compile: unable to infer tagged configuration libtool: compile: specify a tag with `--tag' It doesn't seem to be specific to a certain file, because I'm running with MAKEOPTS=-j2, and get the same error twice, once for each of the first two files that are attempted. The compile command looks like this: /usr/lib/rep/i586-pc-linux-gnu/libtool --mode=compile gcc -c [lots of probably irrelevant compile flags, definitions and include dirs] rep-gtk.c I don't really know much about how libtool works, and particularly not since librep seems to want to use its own libtool, so I don't really know how to fix this.
As a workaround, you can build both librep and rep-gtk with the same CC envvar set (meaning: run CC=i686-pc-linux-gnu-gcc emerge -1 librep rep-gtk -- except the CC value will depend on your system). *** This bug has been marked as a duplicate of 70514 ***
