After R&D, I found solutions for this ... and its work for me ...
-> This error also appears in bugs.debian.org , and a fix allows you to avoid this error.
-> And another solution (I prefer this):
Download pfbfer.zip and extract it.
Now put all the files of this pfbfer in ...
/usr/lib/python2.7/dist-packages/reportlab/fonts/(put the files)
reportlab, extract pfbfer.
