Hello John,
thanks for your comments.
10.) You are giving instructions in your readme how to compile it in ubuntu. On a fresh install of Ubuntu 10.04 I needed the following not mentioned packages to get it building: build-essential, libboost-dev, [libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev | libboost-all-dev], libssl-dev and libdb4.8++-dev. Actually it didn't build, because setPlaceholderText in QLineEdit was introduced in Qt4.7 and Ubuntu 10.04 comes with Qt4.6. I commented them out.
I'll update the instructions... I've also changed the placeholders to only be compiled for Qt 4.7+.
Regarding the build instructions: you can remove "libboost-all-dev" as it was meant as an alternative to installing the smaller packages. -all-dev includes them.
I pulled your changes but it doesn't compile because of another occurence of setPlaceholderText in the file ui_sendcoinsdialog.h generated from sendcoinsdialog.ui (addAsLabel).
