Im shure that I compiled cupsd with the option debug. I have seen that if
one use "make install" the binary will be striped) so I copied the  file
scheduler/cupsd manually.

> file cupsd
cupsd:          ELF 32-bit MSB executable SPARC Version 1, dynamically 
        linked, not stripped

> ll cupsd
-rwxrwxr-x    1 root     other     1955876 Sep  2 09:11 cupsd

/usr/local/lib/libcups.so.2:    ELF 32-bit MSB dynamic lib SPARC Version 1, 
        dynamically linked, not stripped


But the debugger output is the same as before ...
