Debian Question

[chip33az at netscape.net]

I have a question about compiling packages on Debian.

I would like to move back to Etch since I feel it is more stable (and 
for some reason the networking is faster) than my current Gutsy install.

Most of the programs I can use the default Etch with no issues, but 
there are some I would like to either install myself or compile myself. 

For example, I would like the latest GNUCash (helping me with my 
accounting class) and Iceweasel and Icedove.

Any issues with installing/compiling these?  I have used Debian for a 
long time, but typically just do the apt-get/aptitude route.

Thanks for any guidance.
