Hi,
where can I found a repo that has a php-mcrypt for CentOS 6 x86-64?

Remi has it.

http://rpms.famillecollet.com/enterpris ... crypt.html

I'm using rpmforge repo also, do you think that I will have problem with REMI?
How can I install REMI on CentOS 6 64 bit without problem?

Thanks!

Not really advisable to mix repos, but basically you would:

Install remi and epel according to http://blog.famillecollet.com/pages/Config-en
Edit /etc/yum.repos.d/rpmforge.repo and add includepkgs=package 1 package2 package3 to restrict it to just the packages you use from rpmforge.
Edit /etc/yum.repos.d/remi.repo to enabled=1 and add includepkgs=php*
yum update
yum install php-mcrypt

Add any extra packages to includepkgs if you get any missing dependency errors.

Thanks for the reply.

Is there a way to know whick package has been installed from REMI and EPEL?

yum list installed | grep @epel
yum list installed | grep @remi

really really thanks for the answer, I appreciate it.

Hi,
I'm using centos 6.0 x86,
I also have problem with php-mcrpty, any help?

yum install php-mcrypt

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

You can't use the centos5 epel repo with centos6.

Thank you! This is it, I solved this problem
