ELF interpreter /libexec/ld-elf.so.1 not found

On a recently installed 8.0RC1 system I am getting this when trying to 
start the cups printing daemon:

# cupsd
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap: 6

A listing of the directory shows the following:
ls -l /libexec/
total 544
-r-xr-xr-x  1 root  wheel  249544 Oct 10 07:14 ld-elf.so.1

It also happened when I tried to start firefox35 that was installed as a 
package.  After deleting the package and installing from ports, firefox 
now works.

I tried to install cups from ports, but I still have the problem.
Any help is appreciated.

TIA
