[PHP-INSTALL] Help mcrypt supported cyphers none

[Clayton A. Burnham]

When I look at my phpinfo
mcrypt
mcrypt supportenabled
version>= 2.4.x
Supported ciphers none
Supported modes none

DirectiveLocal ValueMaster Value
mcrypt.algorithms_dir
no valueno value
mcrypt.modes_dir
no valueno value


I get: 
supported ciphers none
supported modes none

What am I doing wrong?

Thanks
