[CIG-SHORT] the netcdf option in pylith installer

[Brad Aagaard]

Hongfeng-

This is likely a libtool issue. Some older libtool versions don't 
automatically add the -fPIC flag resulting in this type of error. The 
first thing to check is whether the library source files compiled with 
the -fPIC flag? If not, run
export CFLAGS=-fPIC CXXFLAGS=-fPIC FFLAGS=-fPIC
before running configure.
