R Package compilation problem with Fortran

I typically use R from within X11 but when installing packages I 
typically used the Aqua GUI...

So from within the GUI...I select 'Packages & Data' --> 'Package 
Installer'  and after selecting the Hmisc package, I then click on 
'Install Selected'.  Then I received the error that g77 is not found.

In addition, from within the R console, typing system('which g77') 
yields '/sw/bin/g77'

How did attempt to compile the package? This is clearly an issue 
with setting your PATH correctly. Running R CMD INSTALL (or R 
itself) in the same shell that has the PATH you describe should 
work. But I suspect that's not what you're doing ... therefore it's 
important to know how exactly you try to install it ...

I have not used R CMD INSTALL before.  So I downloaded the package 
source onto my Desktop, unzipped it, and then typed:  R CMD INSTALL 
/Users/brianbeckage/Desktop/Hmisc

Any ideas?

Thanks again for your help.
