* cad/qcad itself:
1. Enable parallel build.
This is safe, because the vendor's script supports it
(but only, when one is using distcc).
2. Remove the special handling for Alpha.
I guess, this is a historical wart --
the current version of qcad compiles on my amd64 with
`-Wall -W' without any warnings. If Alpha bites again,
the wart can be put back until someone tracks the bug down.
* cad/qcad-partslib:
1. Fetch the .tar.gz, rather than .zip variant of the distribution.
This new file is more than twice smaller.
2. Remove build-dependency on qcad -- this is useless for a pure-data port
and only complicates package building and installation
(a PORTREVISION bump in qcad itself, for example,
will necessitate rebuilding partslib without any good reason).
3. Don't create an intermediate extraction under ${WRKSRC}
for the sole purpose of creating PLIST -- extract from ${DISTFILE} into
${DATADIR} directly and use tar's output to create PLIST on the fly.
This saves a ton of I/O and diskspace during packaging.
