Brewing polymake on Debian 11 -- missing EXTERN header file #5

Hi,

I am brewing polymake on a fresh Debian bullseye, and I get the following message:

The formula will only work on some versions of MacOS, sorry. For Debian, polymake is available in the usual apt repositories, via apt install polymake.

The particular error you see above says that a header of the perl C library is not found. This is always installed, but not at the standard location, on MacOS. Hence, the path is set explicitly. It may or may not be installed on your Debian, and it will most likely be at a different location. You can fix this in the formula (perl_cpath), but I would expect more errors.

On the other hand, the formula installs lots of things missing in MacOS, but present in most Linux installations. So installation via apt on Debian is, in our view, the much better option, and we don't support Linuxbrew.

Ok! Good to know! I will install it using apt!
