You are confusing the naming convention for shared libraries that are 
intended to be linked into programs (or other libraries) at build time, 
which normally have to be named libsomething.so because that is what 
the compiler/linker flag -lsomething resolves to, with the naming 
convention for shared libraries that are intended to be loaded at 
run-time (sometimes called plug-ins), which require no particular 
naming.

Examples:

$ ls -1 /usr/lib/postgresql/8.1/lib/
ascii_and_mic.so
cyrillic_and_mic.so
euc_cn_and_mic.so
euc_jp_and_sjis.so
euc_kr_and_mic.so
euc_tw_and_big5.so
latin2_and_win1250.so
latin_and_mic.so
pljava.so
plpgsql.so
...

$ ls -1 /usr/lib/samba/vfs/
audit.so
cap.so
default_quota.so
expand_msdfs.so
extd_audit.so
fake_perms.so
full_audit.so
netatalk.so
readonly.so
recycle.so
shadow_copy.so

$ ls -1 /lib/security/
pam_access.so
pam_debug.so
pam_deny.so
pam_env.so
pam_filter.so
pam_ftp.so
...

$ ls -1 /usr/lib/apache2/modules/
httpd.exp
mod_actions.so
mod_asis.so
mod_auth_anon.so
mod_auth_dbm.so
mod_auth_digest.so
mod_auth_ldap.so
mod_cache.so
...

$ ls -1 /usr/lib/valgrind/x86-linux/
...
vgpreload_core.so
vgpreload_helgrind.so
vgpreload_massif.so
vgpreload_memcheck.so
