R SIG Debian - Aug 2014 - Is the R package for Ubuntu compiled as a shared library?

Dear all,

I have R 3.1.1 installed on Ubuntu 14.04 from the CRAN repo. Days ago
I decided to give a try to the Eclipse extension for R (StatET). This
extension requires the R packages "rj" and "rj.gd", but
these fail to
install no matter what. There is a long thread going on at the StatET
mail-list, the latest details in this message:

http://article.gmane.org/gmane.comp.ide.eclipse.statet/165

Yesterday a user sent a message saying he encountered the same error
after compiling R without the shared library flag (--enable-R-shlib):

http://article.gmane.org/gmane.comp.ide.eclipse.statet/168

So the question comes down to: is the R version packaged for Ubuntu
14.04 compiled with this option or not?

Any other hints that may help solving this problem are also welcome.

Thank you,

Lu?s

Yes:

edd at max:~$ ldd /usr/lib/R/bin/exec/R  | head -2
        linux-vdso.so.1 =>  (0x00007fffcadd2000)
        libR.so => /usr/lib/libR.so (0x00007fa1e1379000)
edd at max:~$ 

It has been a shared library build since "forever". We used this fact
with
other embedding solution (eg rkward, RInside, littler, ...)

You may need to work with the StatET folks.
