Re^5: Cannot find dependencies when creating packages on ActivePerl with PPM 4

The generated ppd file is coming from Perl tools (ExtUtils::MakeMaker or Module::Build); these make a guess about the package the prerequisites are found in (based on the specified module name), but sometimes the guess is wrong (eg, Win32::OLE is in the libwin32 package, not a Win32-OLE package). Deciding with certainty what package is required requires, ultimately, an internet connection, in order to have access to the CPAN indices where this information resides.

ActiveState, with ppm4, is moving away from specifying package names as prerequisites, and moving to a REQUIRE field, which can specify elements listed in the PROVIDE field (which can be module names). When this gets fully implemented, this problem of needing to map module names to package names will disappear. See this message for details.

This explains a lot. Looks like the same issue that happens with RPM packages on Linux: packagers choose a package name that best fits the requirements.

This would be easier to solve if the PPM is capable to search the available Perl modules inside a PPD package. I would be able, at least, to maintain the dependency list in my PPD file, even if I have to do it manually. I tested all options against Hash-Util, without any results.
