Problem upgrading to 9.1-Release

[Doug Hardie]

I have upgraded my development system to 9.1 without any problems.  This system maintains kernel source and I build a new kernel with a couple extra options there.  The other systems mount /usr/src and /usr/obj from it and do the install.  The first one to be upgraded had no problem with make installkernel.  Rebooted and ran mergemaster -p just fine.  However make installworld dies within a couple seconds with the following error:

install -o root -g wheel -m 444   libc_pic.a /usr/lib
gencat be_BY.UTF-8.cat /usr/src/lib/libc/nls/be_BY.UTF-8.msg
gencat: No such file or directory
*** [be_BY.UTF-8.cat] Error code 1

/usr/bin/gencat exists.  However, ktrace of the make shows:

  3347 make     CALL  execve(0xbfbfd1c8,0x28c35f14,0x28421180)

  3347 make     GIO   fd 2 wrote 6 bytes
       "gencat"

Obviously its not in any of those places.  How can I fix this?
