[Rd] compling errors for sun unix (PR#2702)

[ripley at stats.ox.ac.uk]

1) This is not a bug, and you did not even attach the file correctly.
The output on the console told you what the error (your error) was,
and it would have wasted less time to have sent that.

The place to ask for help is R-help: R-bugs is for BUGS as defined in the 
FAQ.  Inadequate compilation environments are not bugs in R, especially 
when they give such explicit error messages.

2) You seem to be using gcc 2.8.1, and do not have the compatible Fortran 
compiler.  Please seek a competent local advisor to help you with your 
Solaris education.  A less ancient version of gcc (like 2.95.3 or 3.2)
does work on Solaris 2.7 (2.6 being pretty ancient too).

Note, that is not the version of g77 compatible with gcc 2.8.1, and it is
explicitly `experimental'!

That probably means you don't have /usr/local/lib in your LD_LIBRARY_PATH, 
or otherwise your compilers are not installed properly.

That's very explicit.
