Both OSX and Ubuntu offer vim instead of vi, so that is probably where the difference comes from. I just tried it on RHEL5.8 (or rather CentOS 5.8) and it does not work there either...
Something to keep in mind when choosing how to pass commands to ex: When ex (and ed) are reading commands from standard input, they abort with a meaningful exit status at the first sign of trouble. However, with ex, when commands are given as an option-argument (ed doesn't support this), if there's an error, ex will prompt for another command and wait. In this case, for example, if there was no line matching /5555/, ex would not quit. Usually (but not always), this is not ideal.
Also, the output of that command depends on local settings. It may or may not print a line number. If the output is to be processed by a script, this adds unnecessary complexity (either settings need to be overridden or something downstream needs to handle both possible formats).
In my opinion, the simplicity of ed would be an asset for this task.

Using an old debian where ex is ViM 7.0, I see the desired line prepended by its line number. The mystery deepens.
Perhaps it's related to your ex/vi rc file. What if you use /5555/-2p?
