PEAR Mac Installation Issues

[Vivian Jou]

Hello,

I am currently trying to install PEAR onto my Macbook (macOS Monterey 12.0) and am running into several issues. Just as some context, I had previously successfully compiled PEAR on my previous laptop so when I transferred my files to my new laptop, it also transferred the PEAR folder over too. I am also very unfamiliar with terminal. 

These are the issues I'm running into:

1) When I try to run the "git clone https://github.com/xflouris/PEAR.git" line, it asks for my github information and then tells me that password authentication was removed and authentication failed. I think I made a personal access token on github but I'm confused as to how to properly use this access token as it always prompts me for a password and I still get this error even when I paste in my token string.

2) Since I already had the PEAR folder cloned from my previous installation of PEAR on my older laptop, I tried to just skip the first step and cd'ed to the existing PEAR folder but when I tried the "./autogen.sh" command, I get an error stating that there is no file or directory. 

Any help would be greatly appreciated!
