I had a tough time compiling this program, but it turns out, all I needed to do was change one line in the Makefile:
sslsniff_LDFLAGS = -lssl -lboost_filesystem -lpthread -lboost_thread -llog4cpp
sslsniff_LDFLAGS = -lssl -lboost_filesystem-mt -lpthread -lboost_thread-mt -llog4cpp
This is because the program 'requires' libboost 1.35 and Karmic only allows you to use 1.34 or 1.38. I installed 1.38 by typing 'apt-get install libboost1.38-dev'.
