After upgrading MacOS to 10.14.2 Mojave, I'm not able to install any Ruby Version with RVM anymore. It always gives an error like this:
$rvm install 2.5.3
ruby-2.5.3 - #removing src/ruby-2.5.3..
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.14/x86_64/ruby-2.5.3.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
Certificates bundle '/usr/local/etc/openssl@1.1/cert.pem' is already up to date.
Requirements installation successful.

There has been an error while running make. Halting the installation.
Looking into make.log, the only errors are like this:
making srcs under enc

What I've tried so far:
Nothing of this nor any other tips of similar questions helped.
Any ideas? Or any idea what caused the error libtool: object: dln.o malformed object (unknown load command 1) and how to fix it?
I ran into this issue as well. In my case it was due to MacPorts being outdated after I upgraded to (MacOS) Mojave.
I followed the steps listed on MacPorts' migration guide here: https://trac.macports.org/wiki/Migration
Closed and reopened Terminal (just b/c)
ran rvm install ruby and got Install of ruby-2.6.0 - #complete, hooray!
