dependency on hdf4

     Type:  defect   |     Status:  new
 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.1.3
 Keywords:           |       Port:  hdf4 hdfeos
---------------------+--------------------------------
 I was recently trying to install `hdfeos +szip`, and its configure step
 gave me the following error:
 {{{
 checking for hdf4 szip decoding filter... no
 checking for hdf4 szip encoding filter... no
 configure: error: HDF4 was linked without SZIP, but --with-szlib was given
 Command failed:  cd
 "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_hdfeos/hdfeos/work/hdfeos"
 && ./configure --prefix=/opt/local --disable-dependency-tracking --with-
 hdf4=/opt/local --with-jpeg=/opt/local --with-zlib=/opt/local --enable-
 shared --disable-dependency-tracking --with-szlib=/opt/local
 Exit code: 1
 Error: org.macports.configure for port hdfeos returned: configure failure:
 command execution failed
 DEBUG: Error code: NONE
 }}}
 After that I reinstalled hdf4, this time using the `+szip` variant for
 that, and after I did that, `hdfeos +szip` built successfully. To fix
 this, hdfeos's portfile should include something like the following inside
 its szip variant:
 {{{
 require_active_variants hdf4 szip
 }}}
