The main change seems to be dropping the "0" version. Does replacing
'("0") with '("0" "") also work, so that a versionless name is tried
when the versioned name fails?

I've pushed a set of changes along those lines, plus falling back to
"libpng" when "libpng12" fails and dynamically detecting the libjpeg

Won't "libpthread" get loaded auomatically when "libcairo" is loaded?

I think that's because the libjpeg version 64 wasn't supported by
"jpeg.rkt" --- now fixed.
