Centos 5.1 install convert error about chm2pdf HOT 2 OPEN

Either your CHM file cannot be parsed correctly (reason not clear to me), or you
don't have access rights to the /tmp dir. In the second case, open the chm2pdf 
script
and change "tmp" to your home dir in these two lines:

CHM2PDF_TEMP_WORK_DIR='/tmp/chm2pdf/work' 
CHM2PDF_TEMP_ORIG_DIR='/tmp/chm2pdf/orig'

Before you do this, doublecheck that you have all required packages:

the real problem is another: chm2pdf relies on a couple of os.system() over
'enum_chmLib' and 'extract_chmLib'.
These bin files are not build (and installed) by default in chmlib packages (as
they're just examples of how to use the lib).
I just made a patch to "reimplement" in python the 2 programs using the pychm 
lib.
Maybe you can look at it.
