Engineering Elixir Applications: ERROR: build failed

Installing the mentioned version of erlang gave me issues (I also tried with some other versions in 26.2…)

❯ asdf install erlang 26.2.1

... done.

To overcome this, I had to:
ulimit -n 4096

to increase open file limits… might have helped but I also:
❯ brew install autoconf wxmac openssl@1.1 fop

with some issue with openssl@1.1

Anyway asdf list erlang lists it now and i could install the rest with asdf install and the tools version file.
