Hi Andreas,
just a few thoughts. The symbols you are looking for are in liblapack:

   $ sudo apt install eigensoft pax-utils
   $ symtree /usr/bin/pca
   ...
   liblapack.so.3 => dgetrf_,dgetri_,dsygv_,dgetrs_,dspev_,dpotrf_
   ...

If you add -llapack to the list of libraries, it will pass this step. It will fail
later, but adding also -lpthread and -llapacke will make it build.

That said, it sounds tricky, because there is zero guarantee that
these dgetrf_ functions have the prototype that is in src/eigx.c (they
don't seem to be public). This looks very error-prone.

Cheers,
Tomasz
