I'm a big fan of read.xls, too.

perl might not be in your path any longer. You can test this within R with

system("perl --version")

If you can find it on your system, (try system("whereis perl")) you
can add it to your path or pass the full command to read.xls with
e.g., perl="/usr/local/bin/perl".
