[BioC] hexbin 1.1-4 problem

[Liviu M Vladutu]

I have a box running Redhat FC2, R-2.0.1 and Bioconductor 1.5.
I've installed among other packages "affy" and tried:
library("affy") it went OK (first time).

After, I downloaded from devel-site:
http://bioconductor.org/repository/devel/package/Source/ 
hexbin 1.1.-4 
installed it without error (R CMD INSTALL hexbin.tar.gz) , but now when I try again:
library("affy")

I get the following message:
--------------------------------
Warning message:
Incorrect permissions to edit package database,
/usr/local/R-2.0.1/library/liblisting.Rda in: save.locLib(locLibList, curLib)


Any ideas please?
