 Ah, sorry about that. I only looked at the resulting Makefile and
 in patches/, not at actualy cvs diff. I missed the ${SED}.

 I don't have much experience in this area either. I pretty much just
 remembered I had seen a SUBST in some other package's Makefile,
 grepped my way to an example and used that. Looking at it again now
 I realized I completely broke style since the already existing
 substitutions for sbcl used the other method.

 As I understand it you can add any number of substitutions with
 arbitrary names, each one for a different file, as long as you
 add the name of each to SUBST_CLASSES. But then I don't know how
 name clashes are handled (if at all).
 
 I don't know what the general consensus is; my opinion would probably
 be that a combination would be "cleanest". That is, use a nice @GTAR@
 (and @PREFIX@ etc) tag patched in using patchfiles, and then use SUBST
 to actually perform the substitutions. This being only because the use
 of SUBST is more explicit (it would be possible for an automated tool
 to pick it up for example). But for all I know SUBST may have been
 deprecated (anybody want to provide enlightenment as to what is the
 'preferred' method in pkgsrc, for future reference?).
 
 In any case, ASDF-INSTALL is no longer broken - thanks :)
