Error while installing "instantclient-sqlplus-linux32-11.2.0.1.zip" linux

Question

I have a linux box where i just need the oracle client/sqlplus to connect to database. So I downloaded "instantclient-sqlplus-linux32-11.2.0.1.zip" and unzipped it in a directory.It has the following files
-r--r--r-- 1 root deploy 342 Aug 13 21:15 glogin.sql
-r-xr-xr-x 1 root deploy 1501651 Aug 13 21:15 libsqlplusic.so
-r-xr-xr-x 1 root deploy 6909 Aug 13 21:15 sqlplus
-rw-rw-r-- 1 root deploy 441 Aug 13 21:15 SQLPLUS_README
-r-xr-xr-x 1 root deploy 1218075 Aug 13 21:15 libsqlplus.so
So when I try "sqlplus" I get /sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
I have set the ORACLE_HOME and LD_LIBRARY_PATH to the directory where I have these files. What am I missing? Is there anything else I need to install ?

$ ldd ./sqlplus
linux-gate.so.1 => (0xffffe000)
libsqlplus.so => /home/deploy/oracle/instantclient_11_2/libsqlplus.so (0xf7f4d000)

$ ls

$ echo $LD_LIBRARY_PATH
/home/deploy/oracle/instantclient_11_2
$ ./sqlplus
./sqlplus: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
So for some reason it needs libaio.so.1 and it cant find it ?
