Thank you for all your responses. I went route a) to install pasgui binaries - it all works now!!
Frankly, I had few frustrating hours installing codeblocks on Ubuntu. I wish there were more clear and concrete instructions for us, newbies. Because, for example, "Important note for Ubuntu users: To be able to use the Debian packages on Ubuntu Karmic Koala (9.10) and Lucid Lynx (10.04) you have to use the packages from apt.wxwidgets.org, ..." do not speak to me at all.
