Maybe it would be worth adding this check to the validator. "fink
validate <source tarball>" could unpack the tarball e.g. in /tmp and run
a check for /sw/, and the same operation could be run in fink's
maintainer mode on the unpacked tarball (analogous to "fink validate
<debfile>" and the maintainer mode deb-directory validation).
