compilation problem

Hi,

When compiling packages with C/Fortran code, I'm frequently getting 
the
following sort of error at the stage of testing if package can be 
installed
from temporary location:

** testing if installed package can be loaded from temporary location
Error: package or namespace load failed for 'akima' in dyn.load(file,
DLLpath = DLLpath, ...):

Any suggestions about how to fix this?  If it is a PATH problem, how 
do
I set that so that it is correct when I start up R?

Can you start by telling us which Fortran compiler you have installed
(the manual mentions several), and where
/usr/local/lib/libquadmath.0.dylib came from?  AFAIK all the 
recommended
compilers install it in /usr/local/gfortran/lib.

I'd try moving /usr/local/lib/libquadmath.0.dylib aside (and any other
libs that look like those in /usr/local/gfortran/lib).

Thank you.

best,

Ken
