Add a -f before the location of the makefile. And don't need a dollar 
sign nor {} braces.
(In this case you will need to be in the same directory too since it 
references files with relative references.)

$ cd /usr/pkgsrc/lang/python
$ make -V PYPKGSRCDIR -f pyversion.mk                              
../../lang/python27

By the way, pkgsrc offers:

$ cd ../../databases/py-sqlite3/                                    
$ make show-var VARNAME=PYPKGSRCDIR            
../../lang/python27
$ make show-vars VARNAMES="PYPKGSRCDIR PYTHON_VERSION_DEFAULT"
../../lang/python27
