Description of problem:

The pdf2txt command is more difficult to install than expected.  "yum install  python34-pdfminer" does not install python34-six or python34-chardet.  The pdf2txt command does not work without them.

Version-Release number of selected component (if applicable):

EPEL 7

(The problem was found on an x86_64 RHEL 7.2 Workstation but seems like it is likely to apply to any RHEL 7 / CentOS 7 system.)

How reproducible:

Consistently.

Steps to Reproduce:

1. Check that python34-pdfminer, python34-six, or python34-chardet are not already installed.  (I would assume that if they are you could just remove them.)
2. Find or create a sample pdf containing text; call it /tmp/my.pdf
3. yum install python34-pdfminer
4. pdf2txt /tmp/my.pdf


Actual results:

Traceback (most recent call last):
  File "/usr/bin/pdf2txt", line 7, in <module>
    import six

Expected results:

The extracted text of the pdf should be displayed.

Additional info:

After installing python34-six it gets a little farther but fails again,

$ pdf2txt /tmp/my.pdf 
Traceback (most recent call last):
  File "/usr/bin/pdf2txt", line 10, in <module>
    import pdfminer.high_level
  File "/usr/lib/python3.4/site-packages/pdfminer/high_level.py", line 10, in <module>
    from .pdfdocument import PDFDocument
  File "/usr/lib/python3.4/site-packages/pdfminer/pdfdocument.py", line 17, in <module>
    from .psparser import PSEOF
  File "/usr/lib/python3.4/site-packages/pdfminer/psparser.py", line 20, in <module>
    from .utils import choplist
  File "/usr/lib/python3.4/site-packages/pdfminer/utils.py", line 12, in <module>
    import chardet  # For str encoding detection in Py3

After installing python34-chardet it works properly.
