Description of problem:
As shipped in RHSCL, the nodejs building process is supposed to pre-emptively delete unused dependencies from the deps/ directory.

However, there is a tiny typo for the http-parser dependency in the srpm spec file :

---8<----
142 rm -rf deps/npm \
143        deps/uv \
144        deps/http-parser \
145        deps/zlib
--->8----

The directory name is http_parser (underscore, not hyphen) :
$ ls node-v4.6.2/deps/
cares  gtest  http_parser  v8

Resulting in the deps/http_parser/ directory not being deleted as expected.

.... It does not change anything to the end result, but might be worth reporting ☺
