I was the reporter. The problem turns up when you use the
bash 2.04 beta. The problem does not turn up with bash 2.03

The problem is not that c:\djgpp\bin/perl.exe does not get invocated.
Somehow internally in perl c:\djgpp\bin propagates to @INC,
messing up @INC. See the error message:

C:\install\apache>bash -login
Welcome to bash version 2.04.7(15)-release
