Tcpwrap is currently available through PECL
  http://pecl.php.net/package/tcpwrap.
 
  If PEAR is available on your *nix-like
  system you can use the pear installer to install the tcpwrap extension, by the
  following command: pear -v install tcpwrap.
 
  You can always download the tar.gz package and install tcpwrap by hand:
  
| Example 1. tcpwrap install by hand | gunzip tcpwrap-xxx.tgz
tar -xvf tcpwrap-xxx.tar
cd tcpwrap-xxx

./configure && make && make install |
