[R] problems installing odesolve in OS X

[Jorge A Ahumada]

When I try to install odesolve

 > install.packages("odesolve")

I get the following error:

-----------------------
gcc -bundle -flat_namespace -undefined suppress -L/usr/local/lib -o 
odesolve.so bnorm.o call_lsoda.o cfode.o dgbfa.o dgbsl.o dgefa.o

ERROR: compilation failed for package 'odesolve'
** Removing 
'/Applications/StartR.app/RAqua.app/Contents/library/odesolve'
----------------------

and sure enough /usr/local/lib/gcc does not exist in my machine! 
Anybody knows how to get around this? I am using OS 10.3.2, R 1.8.1

thx,
