Darn! Unfortunately I don't think there's any way to avoid problems with semicolons in program_transform_name then, at least not by simply hacking the transform variable. :( I agree with you that the Automake behaviour seems bad here. It should be possible to install untransformed programs into locations like pkglibexecdir. For the MANS primary there is a notrans_ prefix to avoid name transformation, but it appears that this is not an option for PROGRAMS. I don't know why this is; maybe it's something to change in the future. My next suggestion would be to use an install-exec-hook (which runs after the default rules have installed the programs) to rename the affected programs back to their original names.
