in general it makes sense to have an SConscript in each folder where 
your input files are, and a "module" (=program/library/...) gets built. 
This makes it easier to reference filenames within each "module", 
because these names are interpreted relative to the location of the 
current SConscript file.
So, in your case I'd have an SConscript in "lib":

   Import('env')
   env.Libary('mylib', Glob('*.f'))

and another one in "utils":

   Import('env')
   env.Append(LIBS=['mylib'])
   env.Append(LIBPATH=['../lib'])
   env.Program('botoh.x', Glob('*.f'))

. For being able to build both of these "modules" into a Variant dir, 
I'd then add another "SConscript" at top-level:

   SConscript('lib/SConscript')
   SConscript('utils/SConscript')

and finally call this SConscript from the top-level SConstruct with the 
"variant_dir=" option as:

   env = Environment(...)
   Export('env')
   SConscript('SConscript', variant_dir='build')
