Merge pull request #2161 in HDFFV/hdf5 from ~DYOUNG/netbsd:develop to develop

* commit 'ec4418a75716b7f2ce53e627de28d139b281b545':
  In portable shell scripts (using #!/bin/sh) we have to use single square brackets, [ ], instead of the bash-ism double square brackets, [[ ]].
  Make this script work on hosts where PERL is not installed at /usr/bin/perl.
