Well, this seems to be turning into a bit of a band-wagon. Here's my attempt to jump on it. Since I already had about 90% of the necessary code already in my FreeBSD::Portindex stuff, I've added a new 'portdepends' script. This generates a detailed dependency tree printout for a port using the data stored in the portindex cache. Output looks like this: % portdepends textproc/sphinxsearch [......] sphinxsearch-0.9.9 (textproc/sphinxsearch) [.....L] - libiconv-1.13.1_1 (converters/libiconv) [...B..] - - libtool-2.4 (devel/libtool) [.....L] - mysql-client-5.1.55 (databases/mysql51-client) [...BR.] - - openssl-1.0.0_5 (security/openssl) [...B..] - - - makedepend-1.0.3,1 (devel/makedepend) [...BR.] - - - - pkg-config-0.25_1 (devel/pkg-config) [...B..] - - - - - gmake-3.81_4 (devel/gmake) [.....L] - - - - - - gettext-0.18.1.1 (devel/gettext) [.....L] - - - - - - - libiconv-1.13.1_1 (converters/libiconv) [...B..] - - - - - - - - libtool-2.4 (devel/libtool) [...B..] - - - - - - - libtool-2.4 (devel/libtool) [...BR.] - - - - xproto-7.0.16 (x11/xproto) [...BR.] - - - - - pkg-config-0.25_1 (devel/pkg-config) [...B..] - - - - - - gmake-3.81_4 (devel/gmake) [.....L] - - - - - - - gettext-0.18.1.1 (devel/gettext) [.....L] - - - - - - - - libiconv-1.13.1_1 (converters/libiconv) [...B..] - - - - - - - - - libtool-2.4 (devel/libtool) [...B..] - - - - - - - - libtool-2.4 (devel/libtool) [EP.B..] - - - perl-5.10.1_3 (lang/perl5.10) [.....L] - expat-2.0.1_1 (textproc/expat2) The left hand column shows the type of dependency: one of Extract, Patch, Fetch (v. rare), Build, Run or Lib. It's kind of repetitive, unlike Mark Linimon's python script, mostly because I wanted to keep the code relatively simple.
