[R-sig-Debian] rJava works on karmic for root but not for user sean

[Sean O'Riordain]

Good afternoon,
A strange one - library(rJava) works for root but not for user sean

On 64-bit Ubuntu 9.10, using R as root (sudo -i), I can say
  library(rJava)
and it works fine with no error message of any kind.  But logged in as
myself user "sean", it can't start...

The sessionInfo is identical for root

I've un-installed and re-installed r-base and r-cran-*

I've done a reboot; I've done 'R CMD javareconf'

The file /usr/local/lib/R/site-library/rJava/libs/rJava.so and any
nearby files and paths are readable by user sean...

I've searched the archives, I've googled... (possibly missing some
vital clue of course!)

I've removed the personal R library completely - I've checked libPath()

java is available at the commandline both as root and as sean

I've tried adding files to a new file in /etc/ld.so.conf.d   and doing
an ldconfig ... but I can't see how this would be different for root
and sean.

The only thing that I think changed was there was various ubuntu
updates this morning which asked for a reboot - so I did... and was
unable to go with the latest kernel so I'm with a previous version -
I'm not sure it is the same as before.

If I say do a R CMD javareconf I get different results which may be a
clue... but it does appear to point to the same place in the end...

Any help would be appreciated.
