readline fails on Sun machines?

[McIntyre, Terry]

THe following code works on my AIX machines, 
but not on Solaris machines. All are running Perl 5.005_03.

What's the story?

Thanks!

#!/usr/local/bin/perl -w

print "account = " ;
$account = readline STDIN ;
chomp($account);
print "account: $account\n";
