R help - Jul 2002 - R1.5.1 compilation ans install: 2 previous questions

I'm geting ready to compile and install R-1.5.1
(R-patched_2002-07-15.tar.gz) on Linux
(Suse 8.0, 2 AMD proc., ATLAS libs installed). 
My current version is R.1.4.0 

I'd like to get advice on two doubts:

1. Is it better that I remove my current /usr/lib/R directory?

2. Regarding ATLAS, the R-1.5.1 R-admin manual states :
"This is currently not supported. The problem is that SIGINT signals
will not be handled properly when sent during a multi-threaded ATLAS
computation, and this may result in a segmentation fault".

Does this mean that I should avoid the --with-blas=/usr/lib/libatlas.a
option for ./configure ?

Agus

Thanks

It's only an issue if ATLAS is multi-threaded, so it depends on your
ATLAS. (And you might decide to live with the bug, if you have a
multi-CPU system since the speedup can be quite substantial.)
