Installing Spidermonkey returns error

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Get a fresh FreeBSD
2. Have a lot of issues with pynids but get them fixed ;)
3. Follow the guide but get an error

What is the expected output? What do you see instead?

js-1.8.0-rc1-src # make BULD_OPT=1 -f Makefile.ref
"config.mk", line 40: Need an operator
"config.mk", line 42: Need an operator
"config.mk", line 44: Need an operator
"config.mk", line 51: Missing dependency operator
"config.mk", line 53: Need an operator
Error expanding embedded variable.

Assumed that gmake might be necessary resulting in:

js-1.8.0-rc1-src # gmake BULD_OPT=1 -f Makefile.ref
config.mk:159: config/FreeBSD9.1-RELEASE.mk: No such file or directory
cat: ../../dist/FreeBSD9.1-RELEASE_DBG.OBJ/nspr/Version: No such file or 
directory
gmake: *** No rule to make target `config/FreeBSD9.1-RELEASE.mk'.  Stop.

What version of the product are you using? On what operating system?

Latest version JSUN + FreeBSD 9.1

Fix by creating file in the config folder. Copied Linux_ALL to 
FreeBSD9.1-Release.mk and rebuild the file with gmake.
