v8js: natives_blob.bin - not found

I am running CentOS 7 and followed the instructions in README.Linux.md to compile v8. When I try to compile v8js 1.3.2, I’m getting a configure error:

checking for natives_blob.bin... not found
configure: error: Please provide V8 native blob as needed
ERROR: `/tmp/pear/temp/v8js/configure --with-php-config=/usr/local/bin/php-config --with-v8js=/opt/v8' failed

I’m not seeing a file called natives_blob.bin in my v8 directory.

Can you please let me know how to generate this file? I tried installing 1.3.1 instead and the configure worked, but I got a different error during compiling which I believe already was resolved in another issue:

make: *** No rule to make target `/tmp/pear/temp/v8js/v8js_generator_export.cc', needed by `v8js_generator_export.lo'.  Stop.
ERROR: `make' failed

Thanks for your help.
