libtool cannot create a file in /usr/lib/x86_64-linux-gnu/ within pbuilder environment

Hi all,

I'm building cups-filters 1.0.23 package with help of pbuilder, and it
gets stuck on libtool trying to install
/usr/lib/x86_64-linux-gnu/libcupsfilters.so.1.0.0

Here is the relevant part of log:

make[1]: Entering directory `/tmp/buildd/cups-filters-1.0.23'
make[2]: Entering directory `/tmp/buildd/cups-filters-1.0.23'
 /bin/mkdir -p '/usr/lib/x86_64-linux-gnu'
 /bin/bash ./libtool   --mode=install /usr/bin/install -c
libcupsfilters.la libfontembed.la '/usr/lib/x86_64-linux-gnu'
libtool: install: /usr/bin/install -c .libs/libcupsfilters.so.1.0.0
/usr/lib/x86_64-linux-gnu/libcupsfilters.so.1.0.0
/usr/bin/install: cannot create regular file
`/usr/lib/x86_64-linux-gnu/libcupsfilters.so.1.0.0': Permission denied
make[2]: *** [install-libLTLIBRARIES] Error 1
make[2]: Leaving directory `/tmp/buildd/cups-filters-1.0.23'
make[1]: *** [install-am] Error 2

Permissions on /usr/lib and /usr/lib/x86_64-linux-gnu/ within pbuilder look ok:

# ls -ld /usr/lib /usr/lib/x86_64-linux-gnu/
drwxr-xr-x 37 root root  4096 Aug 27 18:30 /usr/lib
drwxr-xr-x 14 root root 24576 Aug 27 18:30 /usr/lib/x86_64-linux-gnu/

If I login to pbuilder environment and run "fakeroot debian/rules
binary" by hand, it works just fine.

Do you have any hints on why would it fail if run by pbuilder in
automatic mode? Where should I look for clues?

Thanks.
