Please specify what version of R you are using and how you installed it.

For this purpose, in the default setup on Debian we have 
/usr/local/lib/R/site-library. When using the R backport from CRAN on Debian 
testing this is what you should get:

 > sessionInfo()
 R version 3.1.3 (2015-03-09)
 Platform: x86_64-pc-linux-gnu (64-bit)
 Running under: Debian GNU/Linux 8 (jessie)

 ...

 [1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"       
"/usr/lib/R/library"

This should usually not be necessary, as you can use the default location of
the local site library.

It looks like you have done something fairly non-standard to your system...

Cheers,
