[R] Building R on Solaris with SUNperf

[Giovanni Petris]

Dear All,

I am building R-1.3.1 on Solaris 2.7 and I am trying to use the native
SUNperf BLAS/LAPACK. I have added the flags ("-dalign
-xlic_lib=sunperf") for the compilers in the config.site file. 
What is not clear to me is what I have to do with the "--with-blas"
flag for ./configure. It seems to me that omitting it is not enough. 
Any suggestions? 

Another question, I guess about how to organize directories and get
rid of obsolete versions of R, is the following. A directory listing
of /export/home/share/R on my machine gives:

Wed<18:17>R[85]#ls /export/home/share/R
library/      R-1.2.0/      R-1.2.2/      R-1.3.1/      R-1.3.1.tgz
 
I keep in "library/" all the packages, and I build each version of R in
the directory with the same name. My question is: can I safely nuke
R-1.2.0/ and R-1.2.2/ once I have a working R-1.3.1?

Thank you in advance.
Best,
Giovanni
