What distro are you in? You need to get a binary version of GCC rather than a source version. RPMs are usually binaries, but not all distros support installing apps from RPMs. Gentoo is almost all source, but it also has binary packages. etc. etc. The solution to this is going to be very largely distro-specific. (A binary package is one that has been pre-compiled on someone else's system.)

Note also that it says that there's no compiler found in your $PATH. Did you do a locate gcc? You might already have GCC somewhere not on your $PATH. If you do, then you can easily add it to your path; if you use bash (and almost certainly you do) it would be done thusly:

export PATH=$PATH:/wherever/gcc/is

(K3B is a great program by the way. But mkisofs and cdrecord are just as good. )

A more important question, which is also distro-specific, is why are you trying to install a program by hand like that? Almost all distros have package management systems which are designed so that you never, ever, ever have to ./configure && make && make install any longer. It would be wise to use the package management system whenever possible. (That is assuming you're using a distro that has a package management system; not all do.)
