[R] R seems to mangle LD_LIBRARY_PATH

[Rolf Turner]

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.

HTH

cheers,
