distribution patch files

I tried to include a distribution patch file in glib-2.34.0 (options.mk) with:

   PATCH_SITES=            http://bugzilla-attachments.gnome.org/
   PATCHFILES=             attachment.cgi?id=224541
   PATCH_DIST_STRIP=       -p1

and got:

   make: don't know how to make /usr/pkgsrc/distfiles/attachment.cgi?id=224541. 
Stop

Just in case it's because of the ?, I tried

   PATCH_SITES=            http://bugzilla-attachments.gnome.org/
   UNQPATCHFILES=          attachment.cgi?id=224541
   PATCHFILES=             ${UNQPATCHFILES:Q}
   PATCH_DIST_STRIP=       -p1

but still no luck:

   make: don't know how to make 
/usr/pkgsrc/distfiles/attachment.cgi\?id=224541. Stop


What am I missing?


Cheers,
