[jeandestouches]

Hello, I use gentoo too (no-multilib profile), mono installs in /usr/lib64/ but eddie-ui expects /usr/lib/ only...
System.DllNotFoundException: /usr/lib/../lib/libmono-native.so

As an experiment, I symlinked those libs to /usr/lib/

ln -s /usr/lib64/libmono-native.so.0.0.0 /usr/lib/libmono-native.so
ln -s /usr/lib64/libMonoPosixHelper.so /usr/lib/libMonoPosixHelper.so

and now eddie-ui beta 2.24.2 (portable) starts without issue.
I hope it will be fixed soon in eddie-ui.
