roracle in linux

Hello.
This is a copy of my email to r-sig-deb

I'm trying install roracle in my debian 64 bit system. I've read the
http://cran.r-project.org/web/packages/ROracle/INSTALL and I've
installed Oracel Instant Client by rpm package (using alien to deb convert).

When I try to install I write

  export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib:$LD_LIBRARY_PATH


in terminal and then I download ROracle_1.1-1.tar.gz from cran and I
type sudo R CMD INSTALL ROracle_1.1-1.tar.gz where I've downloaded the
tar.gz file.

I always get the same error
jose at jose-laptop:~/Descargas$ sudo R CMD INSTALL ROracle_1.1-1.tar.gz
* installing to library '/usr/local/lib/R/site-library'
* installing *source* package 'ROracle' ...
** package 'ROracle' successfully unpacked and MD5 sums checked
configure: error: OCI libraries not found
ERROR: configuration failed for package 'ROracle'
* removing '/usr/local/lib/R/site-library/ROracle'

and I don't understand why. any idea?

Thanks.
