Ubuntu – Liblapack.so.3gf not found

I need to run some analyses in R 2.14 (this old version is needed to run an old package). I'm using 64-bit Ubuntu 16.04 LTS.
I need the quantreg packag in R. But this gives me some error: liblapack.so.3gf and libblas.so.3gf are not found.

However, both packages libblas and liblapack are installed:

> lien@lien:~/R/x86_64-pc-linux-gnu-library/2.14/quantreg/libs$ dpkg -l | grep 'openblas\|atlas\|lapack'

ii  liblapack3       3.6.0-2ubuntu2   amd64      Library of linear algebra routines 3 - shared version

I already tried making a lync for liblapack.so.3gf but this also doesn't work.
I don't have a lot of experience with Ubuntu, and don't really know what else I can try.
