Looking at the above, you're using an RPM version of mcrypt from  
Fedora 28 and you're trying to install a newer version from PECL. It  
is almost always a bad idea to install versions from RPM and PEAR/PECL  
side-by-side. You need to make a choice here for either the RPM  
version or the PECL version.

I can't tell you why the pecl command can't install the newer version  
of mcrypt from PECL, but usually it means it can't compile it due to  
missing dependencies. Unlike PEAR packages (which are essentially  
bundles of PHP files) a package you download through PECL needs to be  
compiled against the PHP version installed on your system. The output  
from the build command will usually hint in the direction of missing  
dependencies,
