I used to have a 32 bit slack current but just upgraded recently and started over installing most of the softwares installed on my old machine.
Been using Arch Linux package for oDesk Team 32 bit (the latest non-beta) and it works with few symlink tricks. (I already forgot the library it used).
Doing the same thing on my 13.37 64 bit machine (haven't gone full current yet), it installs the package but the bin does not execute.
bash: /usr/bin/odeskteam-qt4: No such file or directory
lysender@darkstar:~$ file /usr/bin/odeskteam-qt4
