xlrd required for read_excel put not a requirement in setup.py

[kghose]

I feel that requirements, such as 'xlrd' should be part of the setup.py file and installed when we install Pandas. Thanks!

A small, complete example of the issue

# Your code here
import pandas as pd
pd.read_excel('srep10775-s2.xls', sheet=1)

Expected Output

... should be contents of excel file

Actual Output

    218     def __init__(self, io, **kwds):
    219 
--> 220         import xlrd  # throw an ImportError if we need to
    221 
    222         ver = tuple(map(int, xlrd.__VERSION__.split(".")[:2]))

ImportError: No module named 'xlrd'

Output of pd.show_versions()

xlrd is an optional dependency. you can install it if you wish, but it is not required to use pandas. http://pandas.pydata.org/pandas-docs/stable/install.html#dependencies
