A few days ago I had to rebuild gimp1.1 from source to fix a little bug that was stalling my work. I noticed that since I have LPRng installed on my system, ./configure came up with different settings than the gimp binary in the archive was compiled with (specifically, lpstat support was enabled in the print plugin).
Now it occurs to me that if I were to NMU this package (which I have no intention of doing!), I will be uploading a binary package significantly different from the one in the archive. I imagine this is the case for a great many packages that rely on ./configure and having certain software installed (I don't expect gimp to build-depend on lpr!). Is there a solution to this problem? -itai
