MASTER_SITES!=  ftp -o - 'http://www.cult3d.com/download/viewer/code.js' | ${AWK} \
    -F \" "/${DISTNAME}/{sub(\"${DISTNAME}.tar.gz\","'"",$$2);print $$2;exit}'

Does that work? I thought regular expressions in awk were supposed to be
delimited by '/', not '"'.

Anyway, this situation comes up often enough that maybe a general solution
is called for? Like...

so you only have to write the script "files/getsites.sh" for each
package that has this issue (not tested). The point is, $dynamicsites
is added to the shell code in the _FETCH_FILES macro, which is then
only executed when the script is, when do-fetch is actually run.
