what could cause a script to fail to find python when it has `#!/usr/bin/env python` in the first line?

Trying to get casperjs running on Ubuntu 12.04. After installing it when I run I get:
09:20 $ ll /usr/local/bin/casperjs
lrwxrwxrwx 1 root root 26 Nov 6 16:49 /usr/local/bin/casperjs -> /opt/casperjs/bin/casperjs
09:20 $ /usr/bin/env python --version
Python 2.7.3
09:20 $ cat /opt/casperjs/bin/casperjs | head -4
#!/usr/bin/env python
import os
import sys
09:20 $ casperjs
: No such file or directory
09: 22 $ python
Python 2.7.3 (default, Sep 26 2013, 20:03:06)
[GCC 4.6.3] on linux2
So Python is present and runnable, casperjs is pointing to the right place and it is a python script. But when I run it I get "No such file".
I can fix it by changing the first line of the casperjs python file from:
#!/usr/bin/env python
to:
#!/usr/bin/python
Result:
$ casperjs --version
1.1.0-DEV
I managed to fix it, but I'm wondering why it didn't work with #!/usr/bin/env python, since that seems to be a normal interpreter line. Do I have something configured wrong?
Here are the steps to get casperjs:
$ git clone git://github.com/n1k0/casperjs.git
$ cd casperjs
$ ln -sf `pwd`/bin/casperjs /usr/local/bin/casperjs
$ casperjs
: No such file or directory
