Yes, I use ipkg install. I've tried to install the Hancom apps as well as VisualQ, Qpaint and a couple others. One of two things always happens:
1. There's a dependency that it claims it can't satisfy, so I download the package to satisfy the dependence and it says it's not installing it because all the files are already provided by an identically named package that is already installed. For example, Qpaint requires qpe-base, which requires qpe-embedded. It tells me it doesn't have qpe-embedded, but then when I try to install qpe-embedded it gives me a bunch of "not installing foo because it's already provided by qpe-embedded" messages. I'm paraphrasing a little bit.
2. It seems to install okay, but doesn't run. This is what VisualQ seems to do.
