thanks, 's:^static:extern:' and it works, well sort of. now compilation
gets stuck (waited 3 hours) here:

make[6]: Entering directory `/dev/shm/portage/dev-lang/R-2.15.1/work/R-2.15.1/src/library/tools/src'
mkdir -p -- ../../../../library/tools/libs
make[6]: Leaving directory `/dev/shm/portage/dev-lang/R-2.15.1/work/R-2.15.1/src/library/tools/src'
make[5]: Leaving directory `/dev/shm/portage/dev-lang/R-2.15.1/work/R-2.15.1/src/library/tools/src'
make[4]: Leaving directory `/dev/shm/portage/dev-lang/R-2.15.1/work/R-2.15.1/src/library/tools'

it's apparently running:
/dev/shm/portage/dev-lang/R-2.15.1/work/R-2.15.1/bin/exec/R --vinalla --slave
with 100% cpu usage! i don't what it's doing to be honest :) any idea?

p.s.: i'm attaching the patch to this for the curious, hope it helps.
