I don't know.  I can see that the split makes sense for prefix/exec-prefix 
distinctions, but then again, the disutils will install an entire 
distribution in exec-prefix if it contains "impure" parts, so that's 
certainly an option here.

On the other hand, it's not clear to me *why* the lib-dynload/DLLs 
directories exist, since it seems to me that that's what exec-prefix is 
for.  Perhaps somebody can explain why lib-dynload/ and DLLs/ 
exist?  Perhaps some platforms have to add these directories to some 
godforsaken environment variables like LD_LIBRARY_PATH or something?
