1.5 linux server is a no go :(

[Steven Hartland]

When run via screen just quits with:
Error opening terminal: 
When run from a vt100 ssh session:
Error opening terminal: vt100

truss doesnt give much clue to whats going on:
linux_brk(0x8637000)                             = 140734464 (0x8637000)
linux_time(0x0)                                  = 1067469932 (0x3fa04c6c)
linux_access(0xbfbfe0c0,0x4)                     ERR#2 'No such file or directory'
linux_access(0xbfbfe0c0,0x4)                     ERR#2 'No such file or directory'
write(2,0xbfbfcb60,31)                           = 31 (0x1f)
exit(0x1)
process exit, rval = 256

N.B. OS = FreeBSD
