They apparently build the shared version on Debian, by adding -fPIC to
{C,CXX,FC,F}FLAGS and then after running make they do the following things:

cd src/lib && mpicxx -shared -o libpnetcdf.so.0d -Wl,--soname
-Wl,libpnetcdf.so.0d $(LDFLAGS) -Wl,--whole-archive libpnetcdf.a
-Wl,--no-whole-archive -lgfortran
chrpath -d ./src/lib/libpnetcdf.so.0d

And finally they symlink this lib to libpnetcdf.so

Hope it helps,
Bruno
