error installing WWW::Curl::Easy "Cannot build Constants" MacOS

I'm trying to install the WWW::Curl::Easy module on MacOS10.12.4 and it fails stating "Cannot find curl.h - cannot build constants file".

Curl-config in /usr/bin has an includedir of /usr/include, which does not exist. I checked the Makefile with the perl module, and it lists several other locations it looks, such as /usr/local/include, /usr/local, etc. Those didn't exist, but I made them and copied the curl.h that comes with XCode into them.

I still receive the same error. Here is the log:

I've done my best searches here and on Google, and not finding an answer. I didn't have this issue when I installed this on my last Mac, so not sure what was changed.

This particular error seems to be because the XCode command line tools were not installed. I followed the instructions here: https://superuser.com/questions/995360/missing-usr-include-in-os-x-el-capitan

This still resulted in an error, but it is different and possibly unrelated to this one, so I am considering this question resolved.

You could install Homebrew, and then install curl (brew install curl) which will help a little, but you'll probably run into compilation problems.

I'm no big fan of the WWW::Curl package, though, so might I ask what you are trying to achieve? There are way better "I want to access the interwebz"-packages out there. :)
