[R-SIG-Mac] src based build dying on download.packages

[Vincent Carey 525-2265]

i didn't find any mention of this problem in a google search --
obviously i can work around the following, but i'd appreciate
comments on getting download/install.packages to work in this context.
is this just an indication of a missing repository resource for
this version of R?
