forgot to mention: unfortunately, going with .tar.bz2 distfile for ant-bin
does not play nice with openjdk7:

===>  Extracting for openjdk-7.71.14_1,1
=> SHA256 Checksum OK for openjdk-7u40-fcs-src-b43-26_aug_2013.zip.
=> SHA256 Checksum OK for apache-ant-1.9.4-bin.tar.bz2.
unzip: Unrecognized archive format
*** [do-extract] Error code 1

so for the time being, i've decided to switch every port (ant-bin and
opensdk{6,7}) to use apache-ant-1.9.4-bin.zip.  it is larger, but at least
it allows to get rid of duplicate.
