You will find here a repackaged .deb archive that includes the missing shared libraries and simlinks necessary for MainActor 5.5 to work on Ubuntu 8.04, 8.10, 9.04 and 9.10 (32/64 bits).
Last night, I was searching the Internet for contact information to reach Markus Moenig, creator of MainActor and founder of MainConcept (he is now CTO at DivX), and I found his profile on Linkedin.
