permission denied error

Hello, 

When I try to compile cjs I see this message :

make[1]: Map '/home/roelof/porting_work/cjs/cjs-2.0.0' wordt binnengegaan
 rm -f cjs-console

make: *** [clean] Fout 2
dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2
debuild: fatal error at line 1364:

So the error message is that it cannot make the directory /usr/unused. Permission denied.

The directory is here enabled : 

# noinst_ always builds a static library
if ENABLE_TESTS
testlib_LTLIBRARIES = libregress.la libgimarshallingtests.la
testlibdir = $(prefix)/unused
install-testlibLTLIBRARIES: # prevent it from being installed
endif

What is the best way to solve this ?
