It doesn't seem to 'bite' when invoking a build from a 'seat' using bash or csh 
or sh.

Keeping in mind that scripting WITIHIN Makefiles always has its own 
specification as to which shell is wanted, I wouldn't expect it to matter.
Unless the sh and csh binaries have been removed or over-written?

If someone can tell me which ports exhibit the alleged problem, I'll try it and 
see what happens (no 5.X, but otherwise have 4.11 thru 8-CURRENT ready to hand)..

I will not be surprised if it occurs when building as an 'ordinary user' and 
does NOT occur when building as root....
