18 Hello,
19
20 I have installed sci-libs/blas-cblas-lapack
21 and also sci-libs/atlas
22 as mentioned in an earlier email.
23 However, I can't eselect which flavor of blas-cblas-lapack to use
24 because eselect does not find these modules, i.e.
25
26 # eselect lapack list
27 !!! Error: Can't load module lapack
28 exiting
29
30 If I try to emerge eselect-lapack for example I get:
31
32 # emerge -vp eselect-lapack
33
34 These are the packages that would be merged, in order:
