Comment (by gnwiii@…):

 I decided to use {{{+gcc47}}} on SL.

 {{{
 sudo port -s install R-framework +gcc46
 }}}

 to get:

 {{{
 R-framework @2.15.2_0+accelerate+cairo+gcc47+recommended+tcltk+x11
 (active)
 }}}

 After a long session of reinstalling the R packages that wanted the old
 gfortran dylib this version seems to work properly, but I haven't tried
 any large calculations or run systematic
 checks.


 I choose gcc47 in part because gcc45 has had some problems building the
 hdf5 library which I need for netcdf4.  Overall, considering linux and mac
 problem reports for stuff I use, gcc47 seems to have fixed a number of
 known problems in gcc45 and gcc46, but no doubt has new problems that are
 yet to be reported, and some of the issues for gcc45 and gcc46 have likely
 been addressed with recent updates to the compilers or by workarounds in
 the package sources.

 I'd guess that gcc45 will be "stable" and should work well for most users.
 gcc47 is said to outperform gcc45 in some benchmarks, but may also get
 more updates, so may take a bit more work down the road.  If you do use
 gcc47 and find problems (and report them), the future will be better for
 all of us.

 I also searched for reports of people building R using dragonegg without
 much success.
