[R] Mysteriously vanishing LD_LIBRARY_PATH

[p_connolly at slingshot.co.nz]

Using R-2.8.0 and R-2.8.1, I get behaviour like this:

R version 2.8.0 (2008-10-20)
Copyright (C) 2008 The R Foundation for Statistical Computing
ISBN 3-900051-07-0

[....]

> Sys.getenv("LD_LIBRARY_PATH")
                                                                                
          LD_LIBRARY_PATH
"/home/hrapgc/local/R-2.8.0/lib:/usr/local/lib:/usr/lib/gcj-4.1.1:/home/hrapgc/Rstuff/library/asreml/libs"
> q()
Save workspace image? [y/n/c]: n


However:

R version 2.9.1 (2009-06-26)
Copyright (C) 2009 The R Foundation for Statistical Computing
ISBN 3-900051-07-0

[...]

> Sys.getenv("LD_LIBRARY_PATH")
                                                   LD_LIBRARY_PATH
"/home/hrapgc/local/R-2.9.1/lib:/usr/local/lib:/usr/lib/gcj-4.1.2"


I'm particularly dismayed by the fact that there are now only three
parts to LD_LIBRARY_PATH, and slightly mystified by the appearance of
/usr/lib/gcj-4.1.2 in place of /usr/lib/gcj-4.1.1.  Maybe that's a red
herring since the former is a link to the latter.

I would appreciate help getting the rest of LD_LIBRARY_PATH back.  I
set it in ~/.bash_profile in case that makes a difference to the
possible cause of the phenomenon.

$ uname -r
2.6.18-92.1.22.el5

The problem doesn't seem to arise with Fedora 8 nor with Mepis 6.5.

TIA
