python 2.7 instead of 2.6?

[Erik B. <eb...@fs...>]

Hi,

I followed the install directions for ccplot with success up to testing 
the install of PyNIO. My only deviation from the instructions was to 
(accidentally) use a slightly newer version of Python, 2.7, rather than 
the 2.6.2 that matches my gcc version. My setup:

Quad-core Intel Xeon CPU E5345 @ 2.33GHz CentOS 5 (only standard packages 
from standard repositories except "sshfs" from dag).

Python 2.4, the standard CentOS 5 version is in /usr/bin. Python 2.7 is in 
/usr/local/bin. By default, PATH=/usr/local/bin:/usr/bin

RPM installed software includes gcc version 4.1.2, libpng and 
freetype (including their devel files).

Installed in /usr/local are: Python 2.7, numpy (--fcompiler=gnu95 to match 
lapack/blas), matplotlib, basemap, and GEOS. I was able to test numpy with 
this command:
/usr/local/bin/python -c 'import numpy; numpy.test()'
Running unit tests for numpy
NumPy version 1.5.0b1
NumPy is installed in /usr/local/lib/python2.7/site-packages/numpy
Python version 2.7 (r27:82500, Aug 11 2010, 13:21:14) [GCC 4.1.2 20080704 
(Red Hat 4.1.2-48)]
nose version 0.11.4

Ran 2962 tests in 10.621s

OK (KNOWNFAIL=4)
[But the exit status of the test was zero.]

With those prerequisites installed, I untarred 
PyNIO-1.3.0b5.linux-x86_64-redhat-py262-gcc412.tar.gz to /usr/local, which 
made a /usr/local/lib/python2.6/site-packages directory, so I copied the 
files over to the /usr/local/lib/python2.7/site-packages/. I next ran the 
test listed in ccplot's "INSTALL" file. It failed:

/usr/local/bin/python -c "import Nio; print Nio.__version__"
Traceback (most recent call last):
   File "<string>", line 1, in <module>
   File "/usr/local/lib/python2.7/site-packages/PyNIO/Nio.py", line 145, in 
<module>
     _is_new_ma = get_integer_version(np.__version__) > 10004
   File "/usr/local/lib/python2.7/site-packages/PyNIO/Nio.py", line 138, in 
get_integer_version
     v = int(d[0]) * 10000 + int(d[1]) * 100 + int(d[2])
ValueError: invalid literal for int() with base 10: '0b1'

I tried changing the name of 
/usr/local/lib/python2.7/site-packages/PyNIO-1.3.0b5-py2.6.egg-info to 
PyNIO-1.3.0b5-py2.7.egg-info.

I haven't been able to get it to budge further. I wonder if I ought to 
pull 2.6.2 Python from the CVS tree. Do you have a suggestion?
