can't find libevent-1.1a.so.1 ??

[=?GB2312?B?wM/QsA==?=]

Hi,all,
    i have installed memcached in another new server , but when i
tried to run the server using
"/usr/local/bin/memcached -d -r -m 1024 -l [IP] -p 11211"
it said that
/usr/local/bin/memcached: error while loading shared libraries:
libevent-1.1a.so.1: cannot open shared object file: No such file or
directory

   then i went to http://www.monkey.org/~provos/libevent/ , downloaded
and installed the last version of libevent , and try to run memcache
again . but the same error occured .but the libevent-1.1a.so.1 is in
my server already .

[memcache at z9-1 memcache]$ ll /usr/local/lib/libevent-1.1a.so.1
lrwxrwxrwx    1 root     root           22 Feb  8 22:00
/usr/local/lib/libevent-1.1a.so.1 -> libevent-1.1a.so.1.0.2

  what can i do now ? any hints ?? thank you very much!
