Mac OS: /usr/bin/env: bad interpreter: Operation not permitted

Question

I'm trying to run this script on Mac OS 10.7 (Lion) and I'm getting the error:

$ bbcolors
-bash: /usr/local/bin/bbcolors: /usr/bin/env: bad interpreter: Operation not permitted

I've successfully run this script on other Macs of mine. It's just this script downloaded and unmodified from Daring Fireball.

I found this person with a very similar problem but the accepted answer was that the filesystem had a 'noexe' option on mount. I'm pretty sure that's not the case for me because I've just got it in /usr/local/bin/ and other stuff in there works fine (it also doesn't run from other places or as other users including root).

$ which bbcolors
/usr/local/bin/bbcolors
$ ls -l /usr/local/bin/bbcolors 
-rwxr-xr-x@ 1 nick  staff  9751 Mar 30 19:09 /usr/local/bin/bbcolors

It's a Perl script not a compiled binary, not that that should matter. Here's some extra info for what it's worth:

$ cat /usr/local/bin/bbcolors |head -n 1
#!/usr/bin/env perl
$ which perl
/usr/bin/perl
$ env | grep PATH
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

Did you happen to open/save the file in TextEdit?

That can introduce filesystem metadata (quarantine attribute) leading to the symptom you describe.

Try:

xattr -l /usr/local/bin/bbcolors

and

xattr -d com.apple.quarantine /usr/local/bin/bbcolors

if you see the quarantine attribute.
