On my salix 14.2 system I found the following missing dependencies:
impressive depends on (at least) pygame and python-pillow
pdfchain depends on pdftk
Furthermore, I discovered pdfpc (https://pdfpc.github.io/) which unfortunately is quite outdated (3.1.1). The last version that compiles on an up-to-date salix 14.2 seems to be pdfpc4.1.2 It requires vala and cmake to compile, and it seems it requires libgee instead of libgee1. I would try to update the build files. But all I could find was pdfpc.SlackBuild which is part of the pdfpc package. However it was installed from the salix repository (http://ftp.nluug.nl/os/Linux/distr/sali ... ix/office/) and is not a SBo. Is there a SLKBUILD somewhere?
