Only partially. The right solution is to fix bugs at the source, not
add workarounds for them everywhere else.

This is all good and well, but the preferable solution is to fix the
port so that users can use their distro-provided package manager to
install whatever they want and not need to bother with building it
themselves.

Yes, but it's always better not to litter your system with self-compiled
stuff.

Good for you. Not everyone can or wants to compile from source on their own.

Yes, however some reasonable minimal requirements have to be met.
Like having a non-ancient version of binutils for example.
