[R] How to compile sources?

[Sara Mouro]

Dear all,


I have read the on-line explanations I have found about Building R  
from sources, and istalling Packages from sources...
Also, I have installed gcc4.0 and the gfrotran-4.2.1.dmg.

However, I still do not know how to use them to compile one Source  
(in particular packfor_0.0-7.tar.gz) so that I can use it in R (for  
MAC OS X).

Could someone please explain it to me in an easiest way (i.e. to  
someone who has already "suffered" enough to learn R for herself, and  
knows little about programming)?

Thank you in advance!

Best regards,
Sara Mouro
