For pkgsrc, the easiest way is to just list the dependencies in a README 
file. That's it. Because of the buildlink framework, everything will 
then work. For other systems, you may need more work. :)

Concerning the Makefiles, I suggest you depend on GNU Make or BSD Make, 
since they both have the += and ?= operators, which I consider very 
useful (for CPPFLAGS, you should never use the plain = operator). Yes, 
it means that users will first have to build GNU Make on some systems, 
but portability can even mean: It makes proper use of programs that are 
themselves portable. :)
