Bugzilla Bug 56616

When I try to emerge R (dev-lang/R) without prior emerging f2c, it fails during
./configure stage with error message complaining about missing f77 compiler /
f2c.  I took a look into R-1.8.1.ebuild and found, that on x86 platform it
doesn't depend on neither f77 compiler nor f2c.

Reproducible: Always
Steps to Reproduce:
1. emerge unmerge f2c # To make sure it isn't there ;-)
2. emerge R # Takes quite a long and needs a LOT of memory - and fails...

Actual Results:  
R ebuild failed during ./configure stage

Expected Results:  
Merge R :)

This looks like its fixed in the 1.9.0 and 1.9.0-r1 ebuilds which are in ~x86. 
The fix uses pkg_setup() to check for g77 or f2c, you could probably add the
following to the 1.8.1 and call it 1.8.1-r1:

pkg_setup() {
      if ! which g77 &>/dev/null && ! which f2c &>/dev/null; then
                 eerror "g77 and f2c not found. Maybe the f77 USE flag was not
set when"
                 eerror "you emerged gcc - you could also install f2c"
            die "need g77 or f2c ."
      fi
}

In CVS now, thanks!
