Comment(by kgh03@…):

 the problem lies in /opt/local/bin/h4fc
 $FFLAGS contains the compiler so it appears twice on the command.
 passing -echo flag to h4fc reveals this:

  + eval /opt/local/bin/gfortran-mp-4.5 /opt/local/bin/gfortran-mp-4.5
 -pipe -O2 -m32 -arch ppc -L/opt/local/lib -L/opt/local/lib sd_rd.o
 -L/opt/local/lib -lmfhdf -ldf -lsz -ljpeg -lz
 ++ /opt/local/bin/gfortran-mp-4.5 /opt/local/bin/gfortran-mp-4.5 -pipe -O2
 -m32 -arch ppc -L/opt/local/lib -L/opt/local/lib sd_rd.o -L/opt/local/lib
 -lmfhdf -ldf -lsz -ljpeg -lz
 ld: in /opt/local/bin/gfortran-mp-4.5, can't link with a main executable
 collect2: ld returned 1 exit status
 + status=1
 + exit 1

 removing gfortran from the FFLAGS seems to fix this.

 # FFLAGS="/opt/local/bin/gfortran-mp-4.5 -pipe -O2 -m32 "
 FFLAGS=" -pipe -O2 -m32 "

 tian, if you want a work around for now,

 cp /usr/local/bin/h4fc ~/
 edit ~/h4fc as above.
 then run h4fc as ~/h4fc sds_rd.f

 thanks for all your hard work Takeshi.
