Other tips
If you still have problems while installing some packages, make sure first:
- to install latest XML-SAX. Older versions of XML-SAX may cause warnings.
- to 'perldoc ppm' and 'ppm help'. You'll know many convenient commands and options including 'ppm upgrade -install' and 'ppm install -force'. Note that the number of hyphen is one, not two.
- to search for a newer version of the package from CPAN or its official repository. ppm version is not always the latest.
- not to trust older documents, especially older blog articles. They might be well-known but they tend to ignore recent changes/bugfixes.
