i've got this:

Hydra:/usr/local/lib# ls -l libspandsp*
-rw-r--r-- 1 root staff 2098532 2010-03-07 17:05 libspandsp.a
-rwxr-xr-x 1 root staff     865 2010-03-07 17:05 libspandsp.la
lrwxrwxrwx 1 root staff      19 2010-03-07 17:05 libspandsp.so -> libspandsp.so.2.0.0
lrwxrwxrwx 1 root staff      19 2006-08-02 08:35 libspandsp.so.0 -> libspandsp.so.0.0.1
-rwxr-xr-x 1 root staff  976884 2006-08-02 08:35 libspandsp.so.0.0.1
lrwxrwxrwx 1 root staff      19 2010-03-07 17:05 libspandsp.so.2 -> libspandsp.so.2.0.0
-rwxr-xr-x 1 root staff 1597979 2010-03-07 17:05 libspandsp.so.2.0.0

but whereis command only show 1 version.

Hydra:/usr/local/lib# whereis libspandsp
libspandsp: /usr/local/lib/libspandsp.a /usr/local/lib/libspandsp.la /usr/local/lib/libspandsp.so

should i delete the .0.0.1 just in case?
