How Can I Fix Broken Dependencies
 

Ubuntu 9.04 won't install RealPlayer. At an advanced point in the install program, using gksudo synaptic tells me that I have these broken dependencies:

bsd-mailx
lsb-core

My search in Help and LinuxQuestions hasn't turned up anything on point. Is there some way to fix these so that the install procedure can complete?
Thanks

PS At present I can't see any videos. Is there an alternate way to cure this?

is Realplayer requiring the above mentioned dependencies?. what difficulties that you are facing to get these dependencies?
