I ran this script as a Text Filter:
#! /usr/local/bin/perl
print $^X; # ie. the perl interpreter running the script
and got
/opt/local/bin/perl
I then changed my shebang to /usr/bin/perl
and got, wonder of wonders,
/opt/local/bin/perl
Since I am not an opt person, I moved /opt to the trash.
My scripts then would give a Mac OS X error, so I put it back and got
the error just the same.
It then occurred to me, for no good reason, to (re-)install the
command line tools, and now things behave as I would expect, ie.
$^X ≍ shebang.
I presume this error in my configuration has been there for a long
time and I haven't noticed it simply because the routines I use in
text filters are generally pretty basic and will run in any
interpreter including the 5.8.9 which was in /opt.
Can anyone explain what was happening and why reinstalling the
command line tools fixed it?
