[R-SIG-Mac] Installing igraph

[Thomas]

I've been given an old Mac to run some R programs on and I'm having
trouble setting up. I just need to get igraph working It's OS X 10.5.6
and I have installed R 2.15.3 plus the copy of XCode that came on the
DVD.

For some reason I can't use the package installer. The list of  
available packages appears but I can't install any of them - the full  
error message I get is copied below.

So then I copied the igraph tar.gz file to my machine and in Terminal  
ran R  CMD INSTALL /Users...igraph_0.6.5-2.tar.gz. I get an error  
message saying:

make: gfortran: command not found
Error 127
compilation failed for package

Any advise would be appreciated.

Thank you!

Thomas Chesney
