Error on installation

[DougCurtis]

I've been trying to install Plesk 11.0.9 on my RHEL6 server but I keep running into this error:

Exception: Failed to solve dependencies:
php-imap-5.3.3-14.el6_3.x86_64 requires php-common = 5.3.3-14.el6_3
php-mbstring-5.3.3-14.el6_3.x86_64 requires php-common = 5.3.3-14.el6_3

ERROR: The Yum utility failed to install the required packages.
Attention! Your software might be inoperable.
Please, contact product technical support.

I've even tried installing the php-common package before install but it still gives this error.

Thanks,

Doug
