I’m using DirectAdmin and CentOS 7. I got this error(s) when updating my build:
mcrypt.h not found. Please reinstall libmcrypt
exim not installed
the clamav-freshclam and clamd@scan stopped
So what I did to solve these issues:
wget http://mirrors.ukfast.co.uk/sites/dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-14.noarch.rpm
yum remove epel-release
yum update
rpm -ivh epel-release-7-14.noarch.rpm
yum update
And then rebuild again the custom build. All problems solved!
