[mrtg] Conversion code error

OK, so we have a problem in evaluation.  I can't duplicate it here for some reason, though.

Can you make sure that the last line of the TempConv.pl file is blank?  IE, it ends with \n\n as this MAY confuse some perls on evaluation
Also, remove the initial #! Line - you don't need it.
Finally, just make sure you're not using Unicode when making this file (I notice a Chinese name and so its possible you have Unicode enabled).  It should be plain ASCII.

The error message mentions line 1, EOF which is odd because MRTG prepends 1 or 2 lines to start with.  So, check the permissions on the TempConv.pl file - make sure it is world readable and accessible, although MRTG should catch this case.  It is also possible that your perl has something against 'package' directives.  Finally make sure you don't have multiple ConversionCode directives in the file.
