[R-SIG-Mac] bash R: command not found

[pietro bulian]

Dear all,
I'm a new user of MAC/Unix. I want R on a powerbook MAC with OS 10.3.9. Following instructions I attempted to compile last version of R (2.8). But it was unsuccessful (problems with dlyb). Then I have compiled R 2.6.0, I presume succesfully since with make check all it's OK. Then installed with "sudo make install". Now when I type R in any directory in which an R exist the output is "bash R: command not found". I see R under 
Library/Frameworks/R.framework/Versions/2.6/Resources/bin/exec
Library/Frameworks/R.framework/Versions/2.6/Resources/bin
pietro/Documents/downloads/R.2.6.0/bin/exec
pietro/Documents/downloads/R.2.6.0/bin

is something missing from my PATH?
echo $PATH: sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin

Thanks

Pietro
