Problem running fixit from 5.1rc iso's

I’m hoping someone else can test this and let me know if it is just me or 
not. When I try to start a fixit session from the 5.2rc iso’s I get an error 
message the says:
Warning: ldconfig could not create the ld.so hints file. Dynamic executables 
from the disc likely wont work. 

After I hit enter is says
Warning: could not create the symlink for ld-elf.so.1. Dynamic executables 
from the disc likely wont work. 

After that I can switch to the fixit terminal but all useful commands come 
back with:
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap 

I’ve tried redownloading the iso’s and checked the md5’s everything seems ok 
on that side. I’ve also tried booting from disc 1 and switching to disc 2 
like it asks for and just booting of disc 2 but I get the same results. If 
anyone has any helpful thoughts that would be great because I’d really hate 
to have to rebuild this system.
Thanks
