Python - apache cgi-bin script works/doesn't work with different python installations?

Question

I have a file test.py in my cgi-bin folder for apache. The file looks like this:

#!/usr/bin/python
print("Content-type: text/html\n\n")
print("Hello world!")

Then, if I go to www.<mywebsite>.com/cgi-bin/test.py, the page successfully shows Hello world!

But, if I change my header line in my python script to

#!/home/kalaracey/python2.7/bin/python

when I navigate to www.<mywebsite>.com/cgi-bin/test.py, I get a Error 500 Internal Server error. Any ideas?

I have done sudo chmod 755 test.py and can call it with just ./test.py with both versions of the header line.

EDIT: Per @Anony-Mousse 's comment, here's the Apache error_log that applies:

[Wed Jul 11 17:33:40 2012] [error] [client <ipaddress>] (13)Permission denied: exec of '/var/www/cgi-bin/test.py' failed
[Wed Jul 11 17:33:40 2012] [error] [client <ipaddress>] Premature end of script headers: test.py

@Anony-Mousse I've added the two lines of the error_log that apply; it looks like it's a permissions error? — Kyle L

Does the web server user have access rights to your custom python installation?

If it cannot execute /home/kalaracey/python2.7/bin/python it cannot execute your script.

Make you have chmod -R go+rX /home/kalaracey/python2.7 and chmod go+x /home/kalaracey/python2.7/bin/python.

I executed both of those commands but still nothing. Any ideas? My permissions for ~/python2.7/ are drwxr-xr-x; ~/python2.7/bin is drwxr-xr-x; and ~/python2.7/bin/python is -rwxr-xr-x

Actually, I realized that the permissions for home/kalaracey (i.e., ~) are just drwx------. Changing permissions for it via chmod -R go+x /home/kalaracey allowed the script to run. Thanks for all your help @Anony-Mousse!
