I am using Suse Linux 8.1:

IAHC-LINUX03:~ # uname -a
Linux IAHC-LINUX03 2.4.20-64GB-SMP #1 SMP Mon Mar 17 17:56:03 UTC 2003 i686
unknown unknown GNU/Linux

and R 1.7.1:

IAHC-LINUX03:~ # R --version

I have set my http_proxy environment variable to http://wwwcache.bbsrc.ac.uk,
which is the correct address of my proxy.  When I try update.packages() within
R, it does NOT use my proxy at all:

IAHC-LINUX03:~ # echo $http_proxy
http://wwwcache.bbsrc.ac.uk:8080/
IAHC-LINUX03:~ # R
