[gentoo-user] Do we have to build gcc with fortran now?

[Dale <rdalek1967@gmail.com>]

I just did my updates and ran into this:

* Maintainer: sci@gentoo.org
  * USE:        amd64 consolekit elibc_glibc kernel_linux multilib 
policykit userland_GNU
  * FEATURES:   preserve-libs sandbox

  * Please install currently selected gcc version with USE=fortran.
  * If you intend to use a different compiler then gfortran, please
  * set FC variable accordingly and take care that the neccessary
  * fortran dialects are support.

  * ERROR: sci-libs/blas-reference-20070226 failed (setup phase):
  *   Currently no working fortran compiler is available
  *
  * Call stack:
  *          ebuild.sh, line   56:  Called pkg_setup
  *          ebuild.sh, line 1446:  Called fortran-2_pkg_setup
  *   fortran-2.eclass, line  134:  Called _die_msg
  *   fortran-2.eclass, line  120:  Called die
  * The specific snippet of code:
  *      die "Currently no working fortran compiler is available"
  *
  * If you need support, post the output of 'emerge --info 
=sci-libs/blas-reference-20070226',
  * the complete build log and the output of 'emerge -pqv 
=sci-libs/blas-reference-20070226'.
  * The complete build log is located at 
'/var/log/portage/sci-libs:blas-reference-20070226:20110622-034357.log'.
  * The ebuild environment file is located at 
'/var/tmp/portage/sci-libs/blas-reference-20070226/temp/die.env'.
  * S:

This is my gcc info:

[ebuild   R    ] sys-devel/gcc-4.4.5  USE="gtk mudflap (multilib) nls 
nptl openmp (-altivec) -bootstrap -build -doc (-fixed-point) -fortran 
-gcj -graphite (-hardened) (-libffi) -multislot -nocxx -nopie -nossp 
-objc -objc++ -objc-gc -test -vanilla"

So, does everyone need to turn on the fortran USE flag so that they 
don't break anything?   May I also add, the USE flag description is 
worth about as much as a screen door on a submarine.

fortran - Adds support for fortran (formerly f77)

That doesn't tell me very much.

Heads up for folks about to do their updates, check into the USE flag 
fortran to see if you need to add it to yours before updating a bunch of 
stuff.
