[yocto] error in : $ runqemu qemux86

[Arun M Kumar]

I have built my first image with the Yocto Project build environment, I 
have the image ready.

when I do.

$ runqemu qemux86

I get the following error.

--------------------------------------------------------------------------------
There was an error running bitbake to determine TMPDIR
Here is the output from 'bitbake -e':
ERROR: Unable to parse conf/bitbake.conf: conf/bitbake.conf:18: unparsed 
line: 'xport exec_prefix = "/usr"'

What could be the possible causes to this.

I had to add the scripts directory in Poky to my PATH variable, does 
this gives any hints to my problem ?
