I see a number of problems with this approach: - It is not desirable to enable this on all platforms as there may be no perl in /usr/bin, so it should be possible to disable it during configure - perl may be in another location A solution with a generic program transformation similar to other GNU tools (although during configure) like --program-transform-name=PROGRAM run sed PROGRAM on installed program names would IMHO be more flexible and wouldn't require hardcoding any pathes. Just to be clear: I would expect this solution directly to wget to transform output file names and pathes.
