## this started to look awkward, since the file /usr/lib/libcups.so.2 DOES seem to exist though.

# ls /usr/lib/libcups.so.2
ls: cannot access /usr/lib/libcups.so.2: No such file or directory
## "cannot access" is different to normal "no such file or directory"-messages.

:/usr/lib# ls -altr | grep cup
ls: cannot access libcups.so.2: No such file or directory
??????????  ? ?    ?          ?            ? libcups.so.2
