AAC::Pvoice README As of version 0.5, these modules should be able to run on all platforms supported by Device::ParallelPort. This dependency has to do with AAC::Pvoice::Input, which needs to be able to poll the parallel port in case it needs to communicate with the 'Adremo' electrical wheelchair. For this I'm using Device::ParallelPort, which has drivers for Linux and Win32. As of version 0.6 the modules allow you to use your application in One or Two-button mode. See the documentation of AAC::Pvoice::Input for details. At the very least you should be able to use this set of instructions to install the module... perl Makefile.PL make make test make install If you are on a windows box you should use 'nmake' rather than 'make'.
