As you say, it looks like its missing a library. The first error 
reference is to MythSystemEventHandler which is defined (classed) in 
..../mythtv/libs/libmythtv/mythsystemevent.h
Maybe an include got dropped?
How about pulling down a version you know to be good and diff'ing 
against what you have, to see what's missing and where...since the 
include could have been dropped from a file (unlikely) or inadvertantly 
dropped from a makefile template.
(I haven't seen either of those things happen with mythtv: the builds 
are automatically done as a test, but I have seen that happen with the 
other stuff, particularly missing includes in the xvmc code in the Intel 
driver about a year and a half ago.)
