vua is a simple script to build and package vitasdk libraries from their packages repository. The regular vdpm tool uses precompiled packages, some of which are currently broken and/or outdated (libmathneon).
Install vua by doing
# cp vua $VITASDK/bin
and compile and install packages by running
# vua PACKAGENAME
where PACKAGENAME is a subdirectory of github.com/vitasdk/packages. vua downloads the repository for you in
$VITASDK/packages.
Currently, you need to remove $VITASDK/bin/libmakepkg/tidy/strip.sh, since stripping libraries breakes linking them. I've already submitted a pull-request to vitasdk (vitasdk/vita-makepkg#5) that removes it but it has not yet been merged.
