cdf files for affy function - Bioconductor; update on bioconductor

hi

a) I want to use the affy function on bioconductor. I have R 9.1 and 
Panther on a powerbook G4.

I have installed the package, everything seems fine. One of the 
functions is rma and asks for a cdf file. Those files (the info on 
the affymetrix chips) are downloadable from the bioconductor pages 
and the page does it automatically. Except that for some reason it 
doesn't install it, it gives an error saying there's no package 
called drosgenome1cdf (the file I need)

I know that file is there. I downloaded it manually and still 
couldn't install it.
finally I used some tools from the affy package to make the cdf 
file/package that I need (function: make.cdf.package)
the function run ok, built a package whose folder is in the R 
library, the package manager recognizes it but when I try to install 
it gives the error:
loading package: drosgenome1cdf Error in testRversion(descfields) : 
This package has not been installed properly

I have no idea if anyone can help me here



b) other thing: when I get the bioconductor update from the menu it 
doesn't do it and shows the following error:

Note: argument `lib' is missing: using 
/Library/Frameworks/R.framework/Resources/library

and then:


Error in getVersVals(e1, e2)

since I'm doing this straight from the menu with the mouse, I was 
very suprise it didn't work!


thanks for any help
