Problems with perl modules

There are some problems with modules from CPAN.

Tk-804.027 please use Tk-804.024
There are problems with the module Tk::PNG crashing applications. This may depend on libpng libraries shipped with linux but there are problems with other systems too.
It is not compatible with PAR too.
Please use Tk-804.024, Tk-JPEG-2.014, and Tk-PNG-2.005
PAR-0.85
There are problems with modules containing a DATA section of File::MMagic and Term::Cap
There problems don't come up when KaTeker is running from source code but when an executable PAR binary is started. It seems to be a problem of PAR. The workaround is to put a blank line just before the __DATA__ .
There are compatible File::MMagic and Term::Cap shipped with KaTeker.
Module-ScanDeps-0.46 Module-ScanDeps-0.48
Module::ScanDeps is used to analyse the modules used by KaTeker. It is not used by KaTeker itself. There is a problem raising a warnig. The corrected version of Module::ScanDeps is shipped with KaTeker. The module Module::ScanDeps is fixed by Autrijus Tang and should be in newer releases of Module-ScanDeps.
Tk:Balloon
The balloon supports only arrows on the left side. ...
The module Tk::Balloon (the version 4.%03d from Tk-804.027) is shipped with KaTeker.

Tk::Listbox can raise error messages when dealing with Tk::Balloon.
There is a compatible Tk::Listbox shipped with KaTeker.
Tk::Entry
Tk::Entry can raise error messages when dealing with Tk::Balloon.
There is a compatible Tk::Entry shipped with KaTeker.
