I missed to compile gcc with support for fortran which lapack apparently needs. The thing is, I tried to install it and the build command failed. Even though, portage installed the sandbox, and the package was installed, even though no files was compiled nor installed. Reproducible: Always Steps to Reproduce: 1. Make sure to have gcc compiled _without_ support for fortran. 2. emerge -vp lapack 3. emerge lapack Actual Results: >>> md5 src_uri ;-) lapack.tgz >>> Unpacking source... >>> Unpacking lapack.tgz to /var/tmp/portage/lapack-3.0/work >>> Source unpacked. g77 -O2 -march=pentium4 -pipe -fomit-frame-pointer -c -o cbdsqr.o cbdsqr.f make: g77: Command not found make: *** [cbdsqr.o] Error 127 >>> Install lapack-3.0 into /var/tmp/portage/lapack-3.0/image/ category app-sci /usr/lib/portage/bin/dolib.a: SRC/liblapack.a does not exist man: prepallstrip: strip: >>> Completed installing into /var/tmp/portage/lapack-3.0/image/ >>> Merging app-sci/lapack-3.0 to / --- /usr/ --- /usr/lib/ * Caching service dependencies... >>> app-sci/lapack-3.0 merged. >>> Recording app-sci/lapack in "world" favorites file...

Ditto here (as in #50586). Although lapack stuff is still "in the work", but should have this problem (which is basically recent since gcc-3.3.3-r2 I believe, which made fortran optional). I'll try to get lapack done soon as well. George *** This bug has been marked as a duplicate of 30459 ***
