[pycrypto] python 3, crypto installation issue?

The pyyaml package tries to see if yaml.h is installed for optional speedups, but i know the pyyaml package can work without the c extensions, maybe the pycrypto installer doesn't handle that case?

Linux, as root.
$ pip3 install Crypto

Installing collected packages: Crypto, Naked, pyyaml
  Running setup.py install for pyyaml
    checking if libyaml is compilable
    gcc -pthread -Wno-unused-result -DDYNAMIC_ANNOTATIONS_ENABLED=1

     #include <yaml.h>
    compilation terminated.

    libyaml is not found or a compiler error: forcing --without-libyaml
    (if libyaml is installed correctly, you may need to
     specify the option --include-dirs or uncomment and
     modify the parameter include_dirs in setup.cfg)

Suggestions please?

$pip3 search pyyaml
pyaml                     - PyYAML-based module to produce
                            pretty and readable YAML-
                            serialized data
PyYAML                    - YAML parser and emitter for
  INSTALLED: 3.11 (latest)

So it seems I have pyyaml installed?
