Installer failing on Debian 11.2, solved installing libev-dev

[sdepablos]

Describe the bug
Executing the installer complains about libev.so.4, but installing libpcr3-dev does not solve the issue on Debian 11.2

Reproducing

Here I'm install libpcre3-dev before executing the install and still complains:

sudo apt-get install libpcre3-dev && bash <(curl -sL get.comby.dev)
Reading package lists... Done
Building dependency tree... Done

libpcre3-dev is already the newest version (2:8.39-13).
libpcre3-dev set to manually installed.

/usr/local/bin/comby: error while loading shared libraries: libev.so.4: cannot open shared object file: No such file or directory
[-] comby did not install correctly.
[-] My guess is that you need to install the pcre library on your system. Try:
[*] sudo apt-get install libpcre3-dev && bash <(curl -sL get.comby.dev)

Expected behavior

The expected behavior is for the installer to work.

Additional context

Installing libev previous to install comby does solve the issue

I get the same error on Ubuntu 20.04

I've updated the install script to hint at installing libev:

[-] My guess is that you need to install the pcre and/or libev libraries on your system. Try:
[*] sudo apt-get install libpcre3-dev libev4 && bash <(curl -sL get.comby.dev)

Also please now also use:

bash <(curl -sL get-comby.netlify.app)

instead of previous bash <(curl -sL get.comby.dev)

Very cool! Thank you! Why netlify?

I was running into an SSL cert issue using curl, might be my machine, might be an issue with the cert (the cert seems fine in the browser though). I'll need some more time to investigate, in the meantime the site is hosted on netlify which doesn't give curl this cert issue
