I am unable to compile without scons because the whole suite is necessary. The suite uses scons with some extensions. scons.py implemented as a Python script. I don't know anything about linkers. I tried to use gprof, but the -pg command, but it is incompatible when compiling with scons. Am I out of luck?

That option is for profiling SCons itself, not for profiling the things that SCons builds.  You are going to have to play with CCFLAGS and with LDFLAGS to get your own software built such that gprof will be able to do something with it.
