It is best to use biocLite when installing packages from Bioconductor
AND R since Bioconductor is designed to work with a specific version
of R.  Had you done so, when you installed pcaMethods, all the
dependencies would have been installed simultaneously.  So, go back
and use biocLite to reinstall pcaMethods and everything will come with
it except aroma.light which is only suggested and not required for
pcaMethods.  Then use biocLite to install aroma.light.  That should do

The take-home message is to ALWAYS use biocLite (when possible, which
is basically ALWAYS).
