 Steve Kargl <sgk at troutmask.apl.washington.edu> pointed out the lapack problem.
 http://www.netlib.org/lapack/faq.html#1.25
 
  1.25) Problems compiling dlamch.f?
 
 The routine dlamch.f (and its dependent subroutines dlamc1, dlamc2,
 dlamc3, dlamc4, dlamc5) MUST be compiled without optimization. If you
 downloaded the entire lapack distribution this will be taken care of
 by the LAPACK/SRC/Makefile. However, if you downloaded a specific
 LAPACK routine plus dependencies, you need to take care that slamch.f
 (if you downloaded a single precision real or single precision complex
 routine) or dlamch.f (if you downloaded a double precision real or
 double precision complex routine) has been included.

 slamch.f and dlamch.f are compiled three times.  One time without
 optimizaton and two times WITH optimization!
