Brian,
Thank you for the message. The configure options I used previously
were based on my skimming through the build script for MacOSX in the

using gcc and ifort (see the attached config.log) with a variety of
options. The compilation finishes (side note: I had to define NM
otherwise the configure script failed) and installs. I try to run

however, after searching the archives, I will ask the list for
assistance.
