Subject: sci-libs/lapack: add eselect-ldso USE flag.
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=251f5c99d0ef0a397afc1d01999106577450e534;p=gentoo.git

sci-libs/lapack: add eselect-ldso USE flag.

profiles: mask eselect-ldso USE flags on fbsd and rpath ARCH.

  eselect-ldso USE depends on ld.so to do runtime library switching.
