Richard, Vincent, thanks for your replies.
Qt 4.7.2 is installed on my machine. I used the default configuration when compiling, i.e. I did not force the path to Qt4 with the --with-qt4-dir=/usr/share/qt4/ option suggested in the INSTALL file. As such, I am expecting the setup and the executable to catch the same libraries when run. Unfortunately it does not work. Now, further digging in my machine configuration highlighted the unexpected presence of Qt libraries in /usr/local/lib. These are not 4.7.2 libs and shadowed the 4.7.2 ones. Having them set aside did the job: lyx is now running :-) Thanks for the comments.

It looks like you're trying to run lyx with a different version of Qt than the one which you used during building. Vincent
