Now using gdb to debug the script (and G74svn recompiled from scratch):

This is how I configured G74svn here:
./configure \
  --with-cxx \
  --enable-largefile \
  --with-proj --with-proj-share=/usr/share/proj \
  --with-gdal=/usr/bin/gdal-config \
  --with-python \
  --with-geos \
  --with-sqlite \
  --with-nls \
  --with-liblas \
  --with-cairo --with-cairo-ldflags=-lfontconfig \
  --with-freetype --with-freetype-includes=/usr/include/freetype2 \
  --with-wxwidgets \
  --with-fftw \
  --with-motif \
  --with-x \
  --with-postgres --with-postgres-includes="/usr/include/pgsql" \
  --without-netcdf \
  --without-mysql \
  --without-odbc \
  --without-openmp \
  --without-ffmpeg

Something is pulling in BLAS/openMP, though.

Do we perhaps have a namespace collision?
