gcc lib error

When the gcc setup hits mk-gcc-lib, this error is printed:
You need /us/bin/omf2elf to build ELF library

I search all over the net but couldn’t find any answers. Does anyone here
have a suggestion? This is an install of GNU EGCS version 1.1.2 running on
QNX 4.25B with watcom 10.6 patch B.
