Try find where is `libevent` installed and add it to `LIBRARY_PATH`. I think this dependency is pulled in from libtool library, probably one of the ucx dependency. Usually the libtool package should contain the `-L…` for the library. But the breakage will happen
if one installs the library to a different paths than the one specified during configure.<br>
<br>
These (libtool) magic are wonderful when it works, but so annoyingly difficult to address when it doesn’t
