Sorry I missing the last question.  To answer it: yes perl really is visible
as /opt/perl/bin/perl which bash fails to execute it as the third line
below shows.  In this shell bash execute cygwin perl on line 5.

Are you sure PATH is the same in bash 3 and 4? You only showed the PATH from
bash 4.
Just out of curiosity, what does

perl -e 'print $^X'

print in those two situations? Also, try running

for i in $(echo $PATH | sed -r -e "s/:/ /g"); do ls -l $i/perl; done

in both shells.
