Executable symbolic link results in "command not found"

Things to check:

• Perform an ls -l /usr/bin/prj-python

If it's like:

lrwxrwxrwx (...) /usr/bin/prj-python -> bin/python

The file will actually be searched at /usr/bin/bin/python (that's what xralf tried to say). Fix:

rm /usr/bin/prj-python
ln -s /full/path/to/your/python /usr/bin/python-prj

• If your bin/python is a shell script (aka. wrapper-script) check the #!-line (sometimes called shebang-line) at the first line. If there's a typo like #!/bin/bush that will cause a not found error message also.

You forgot the initial slash before bin/python. This means /usr/bin/prj-python now points to /usr/bin/bin/python. What would you like it to point to exactly?
