LXDE has no developer tools. I tried compiling mtpaint from source and gcc was missing. I installed it and then gtk was missing. I installed that and still got errors so quit tying. Installed kolourpaint instead.
I switched from SL weekly KDE to LXDE because KDE is broke. knotify4 consumes 100% of cpu and I could not make it stop. Fortunately ksnapshot, k3b, and kolourpaint, 3 of my favorite KDE programs, don't require knotify and work fine under LXDE.
If you are going to remove the developer tools for LXDE (probably to fit it on a CD, which doesn't make much sense to me since CDs are not cost effective anymore because they only hold 1/6 of the data that a DVD does but cost only slightly less), then you should make reinstalling them trivial like:
equo install DT
