[BioC] Which package "Multiget" belongs

[Jeff Gentry]

The release 1.4 version of affy is '1.4.32' and the release 1.4 version of
Biobase is '1.4.15'.  The current devel version of affy is '1.5.2' and
Biobase is '1.4.16'.  

So, you're definitely using the devel version of the software.  I suspect
that if you updated to the latest devel affy, that this problem would go
away (I believe that they had a multiget in a slightly older version), or
if you do indeed want to use the 1.4 release versions, switch to using
those and that should also solve the problem.
