HELP - Why does my import fail?

The Oracle versions are identical, FYI. It was sold with Interleaf's RDM product. Hence, I don't have loads of docs to go with it. We do have in-house expertise, but they're stumped.

The export file comes from a Solaris 2.5 system, and is being
imported to another Solaris 2.5 system. Hardware is different,
but I don't know what bearing that has. I get the following

00038, 00000, "Could not find environment character set handle"
// *Cause: self-evident.
// *Action: internal error.

00021, 00000, "operating system error - error code (dec %lu, hex 0x%X)"
// *Cause; Operating system error.
// *Action: Check the OS manual for the error code and take appropriate
action.
00000, 00000, "Import terminated unsuccessfully\n"
// *Cause: Error encountered.
// *Action: Check the preceding error message and take appropriate actions.
 

The first message is "self-evident?" HAH! I know people posting here are routinely
exporting and importing across platforms and OSes, but I'm unable to find out why
this won't work for me. TIA for all advice. --Dave
