[R-SIG-Mac] compilation problem

[Kenneth Knoblauch]

First off, thank you very much.  I followed your instructions and now 
all but  2 of the packages compile without error.

To answer your questions (which are perhaps moot, now), I installed the 
compiler Intel Macs: gfortran-8.2-Mojave.dmg (ca. 87MB, GNU Fortran 8.2 
from F.X.Coudert) from https://mac.r-project.org/tools/.  I don't know 
where /usr/local/lib/libquadmath.0.dylib came from.

As you suggested, I moved aside the common packages between 
/usr/local/lib and /usr/local/gfortran/lib that are in /usr/local/lib, 
and as I indicated, nearly all of the packages compile.  The 2 that 
don't are for other reasons.

Thank you again.
