I encountered a problem with the shebang line using openSUSE.

For testing purposes, I narrowed this down to one of the simplest of scripts (test_shebang.pl): 

#!/usr/bin/env perl -l

print 'Hello, world!';

When I attempt to run this, I get: 

ken@ibm-laptop:~/tmp> test_shebang.pl
/usr/bin/env: perl -l: No such file or directory

It's not a $PATH or permission issue: 

ken@ibm-laptop:~/tmp> echo $PATH
<list of unrelated paths>:.
ken@ibm-laptop:~/tmp> which test_shebang.pl
/home/ken/tmp/test_shebang.pl
ken@ibm-laptop:~/tmp> ls -l test_shebang.pl
-rwxr-xr-x 1 ken users 48 Mar 24 10:29 test_shebang.pl

I've checked for any problematic characters that might have been present, but found none: 

ken@ibm-laptop:~/tmp> cat -vet test_shebang.pl
#!/usr/bin/env perl -l$
$
print 'Hello, world!';$
$

When changing the shebang line to any of the following, the scripts run with expected output (i.e. prints "Hello, world!" with or without "\n"): 

#!/usr/bin/env perl
#!/usr/bin/perl -l
#!/usr/bin/perl

[download]

The '-l' switch appears to work correctly from the command line: 

ken@ibm-laptop:~/tmp> perl -e 'print "Hello, world!"'
Hello, world!ken@ibm-laptop:~/tmp>

[download]
ken@ibm-laptop:~/tmp> perl -le 'print "Hello, world!"'
Hello, world!

The platform is "openSUSE Leap 42.1" and the Software Updates notification is telling me "Your system is up to date" (after running "Check For Updates"). Other relevant info: 

ken@ibm-laptop:~/tmp> perl -v | head -2 | tail -1

I'm using a borrowed laptop (the owner is not currently contactable) and I'm not overfamiliar with openSUSE: perhaps I just need to tweak a setting. Neither Super Search nor Internet searches have proved fruitful.

Any help would be appreciated.
