man perlrun says that -P causes the script to be run through the C
preprocessor before being executed by perl. So I created a small file
date.pl:

bash$ cat /tmp/date.pl
#!/usr/bin/perl -P
print __DATE__, "\n";

and got this when I tried to preprocess it:

bash$ gcc -E - < /tmp/date.pl
:1: invalid preprocessing directive name
# 1 ""
#!/usr/bin/perl -P
print "Sep 27 2000", "\n";

So maybe the preprocessor error is upsetting perl?

Why not preprocess the file before installing?
