Can't hazard a guess as to why R is tacking on those other components to
LD_LIBRARY_PATH but it seems that if you use Sys.setenv() from within R
you can put your personal directory first. Something like:
Sys.setenv(LD_LIBRARY_PATH=paste("~/install/lib",
Sys.getenv("LD_LIBRARY_PATH"),sep=":"))
You could put that line into your .Rprofile so that you wouldn't need to
enter it on each startup.

I've seen some reference to $R_HOME/etc/ldpaths but I don't have access
to system files, and I definitely don't want this visible to other
users.
I ran into this under Open MPI, but the previous example didn't use MPI
at all.
I'm picking up the wrong libraries; what do I need to do so that my
personal library is searched first?
Running Debian squeeze.
