Programming

Hi Guys.
I have downloaded metamail from internet e I´m trying to compile it at a SCO 5.0.5. In this server it´s working fine (let´s name it as mission1)
i´m using the developer package in this server (mission1) and when I use mailto, i got the e-mail fine. It´s forwarding to a exchange server fine.
I´m trying to make a script to install it on all servers I have (about 30). But (the word ....) when I make some copies of the binaries to another server (let´s name it mission2), it´s doesn´t works ....
I got the following message after type everything on mailto

dynamic linker: mailto: symbol not found:nuname
splitmail: Could not find the end of the headers!
Killed

Does anybody can help me to solve this problem?? I´m sure that´s could be a very simple issue, but I only want to put metamail on SCO. btw, the mission2 is a SCO 5.0.4 server.

2 things:

Either the systems are not identical, or there are some shared library missing

Sorry. I haven´t told that I already know that the OS´s are diferent. The question is: how do I solve this problem? The only shared library reported is /usr/lib/libc.so.1 (wich is really diferent, but it from OS core, and cannot be changed without some procedures, the ones I don´t know).
Can anybody help me?
