the scipy package in gentoo is currently masked and cannot be installed. The problem is not in scipy but in one of the dependencies which, at least in my case, is blas. Does anybody know if it is possible to install scipy with an alternative library?

Below are notes I wrote to myself to get scipy and matplotlib to install on gentoo: Put these lines in /etc/portage/package.keywords app-admin/eselect-blas ~amd64 app-admin/eselect-lapack ~amd64 dev-python/matplotlib ~amd64 dev-python/numpy ~amd64 dev-python/python-dateutil ~amd64 dev-python/pytz ~amd64 sci-libs/scipy amd64 --- emerge -av blas-reference eselect eselect-blas virtual/blas #scipy requires lapack and numpy, matplotlib requires numpy. #numpy does not require lapack but can use it. #lapack-reference requires a fortran 77 compiler. #gcc-4.X has gfortran, a fortran 95 compiler. #Need to use gcc-3.x emerge -av =sys-devel/gcc-3* #switch compilers: gcc-config -l gcc-config x86_64-pc-linux-gnu-3.4.6 source /etc/profile emerge -av virtual/lapack lapack-reference eselect-lapack #switch compilers back: gcc-config x86_64-pc-linux-gnu-4.1.2 source /etc/profile emerge -av numpy matplotlib scipy I have not gotten eselect-blas or eselect-lapack to work yet (maybe that's why they are masked <g>) but with blas-reference virtual/blas lapack-reference and virtual/lapack installed, portage is smart enough to use them when installing scipy. I've used blas-atlas and lapack-atlas in the past but since they take so long to compile and I don't do much linear algebra, the reference ones are OK for me.
