I reported this to Sam. I think there is a problem in the automake stuff that causes configure to generate a Makefile that uses binary install rather than script install for these files. Binary installs run the strip command, which fails for scripts on BSD at least, maybe Linux strip just ignores this.
The ugly ugly kludge I used was to edit work/courier-0.45.3/courier/Makefile and remove references to -s on install commands (leave cmp -s alone).
I'm aware of this issue. I'll try to do something.
