FreeBSD 5.3-RC1 problem on IBM @server 325 type 8835

[Ganbold]

Hi,

I have problem installing world after cvsup.
make buildworld, buildkernel, installkernel went OK. I rebooted afterwards, 
did mergemaster -p.

However installworld says:

btxld: No such file or directory

I searched freebsd mail list archives and didn't find any solution.
There was mentioned to go to btxld directory and make install clean. 
However it didn't worked.

Any ideas?
