I have a Mac on Mojave, and it's failing to install some of the basic stuff required for development:
$ rbenv install 2.6.0

I found several blogposts talking about how the Mojave release has broken a few things for developers, but none of the articles provide a solution. Has anyone else faced the issue described above?
Reposting my response from this other thread - I was facing a similar issue and can recommend the approach below that's related to binutils needing to be uninstalled first. What worked for me:
brew uninstall binutils
# Uninstalling /usr/local/Cellar/binutils/2.33.1... (134 files, 167.6MB)
rbenv install 2.6.5 && rbenv local 2.6.5 ;
# Downloading openssl-1.1.1d.tar.gz...
# -> https://dqw8nmjcqpjn7.cloudfront.net/1e3a91bc1f9dfce01af26026f856e064eab4c8ee0a8f457b5ae30b40b8b711f2
# Installing openssl-1.1.1d...
# Installed openssl-1.1.1d to /Users/auser/.rbenv/versions/2.6.5
# Downloading ruby-2.6.5.tar.bz2...
# -> https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.5.tar.bz2
# Installing ruby-2.6.5...
# ruby-build: using readline from homebrew
# Installed ruby-2.6.5 to /Users/auser/.rbenv/versions/2.6.5
Prior to this the I was also getting a number of varying messages in ruby-build.log - with the last being:
# ld: symbol(s) not found for architecture x86_64
A number of other steps that I took as part of my homebrew setup (prior to uninstall) included:
brew install perl ruby rbenv
# // UPDATE PATHs with suggestions made by brew during install
which awk perl
# /usr/local/bin/awk
# /usr/local/bin/perl
# ^^^ IN SHORT ALL PATHs should be with /usr/local/opt OR /usr/local/bin
You can re-install binutils again after as needed and remember to repeat the uninstallation with any future rbenv install version(s) that you're likely to re-execute (note to self).
PS - tested on macOS Catalina 10.15.3 (19D76) successfully installing both 2.4.0 & 2.6.5
