Installing packages "xslx" on Ubuntu (32bit)

Hi,

I just recently changed my OS to Ubuntu 12.04 (32bit). Now I tried to install some packages required by my old and working scripts. Unfortunately I fail when trying to install the package "xslx". Maybe it is related to the 32bit version of my R (its not possible to install a 64 bit version).

Can anyone help me to sucessfully install xslx?

Here some console output (e.g. sessionInfo()):

install.packages("xslx")

Installing package(s) into '/usr/local/lib/R/site-library'

Any suggestions?
