i)   I know little about MEPIS, and in particular R on MEPIS. Take
everything with a grain of salt, and if in doubt, test on a proper Debian
machine. Try to find one somewhere at nevada.edu. It will easier for us to
get it to work there -- and let's then try to apply what we learned on your
MEPIS box.

ii)  The (autogenerated) quantreg package I sent you has Depends as
follows:

edd@chibud:~> dpkg -f
src/progs/perl/cran2deb/builds/r-cran-quantreg_3.50-0.r2d.1_i386.deb

     Notice how it says "atlas3-base | refblas3 | libblas.so.3"  What you
     need is a concrete package that provides the virtual package
     libblas.so.3.

     You tried atlas3-base, and it didn't work.  The next thing to try
would be refblas3. Install that and see what it does.

     Afterwards there are the others:

edd@chibud:~> apt-cache showpkg libblas.so.3
Package: libblas.so.3
Versions:

Reverse Depends:
  r-cran-matrix,libblas.so.3
  r-cran-rscalapack,libblas.so.3
[...]
Dependencies:
Provides:
Reverse Provides:
refblas3 1.2-6
atlas3-sse2 3.6.0-19
atlas3-sse 3.6.0-19
atlas3-base 3.6.0-19
atlas3-3dnow 3.6.0-19
edd@chibud:~>

     Anyone of those after the "Reverse Provides" will do, but the
     hardware-optimised ones (atlas3-sse2, -sse2, -3dnow) only makes
     sense on the matching hardware.

Hope this helps, Dirk
