One issue you could run to is that dpkg-buildpackage (at least the
version in squeeze, the latest upload has reverted this) exports a set
of CFLAGS etc.

If your software overloads CFLAGS for required flags or just doesn't
compile with the default CFLAGS ("-g -O2 -Wall" I believe), this could
be the problem.
