You need the dev(el) files as well. And it sounds like you need to recompile the source and install again.
You should have no error before you go futher with "make install"
Download Source again.
Go into the folder where you have extracted the package.
do "./configure"
When this is done without any errors (could get these features are disabled)
Then do "make"
Another waiting
If this are ok with no errors at the end
do the make install .
The write gambas2 and you should be sett.
