When I run scons without setting any paths it exits gracefully with a
message that I need to install the latest UFC:

$ scons
scons: Reading SConscript files ...
Checking for pkg-config... yes
[snip]
Checking for ufc-1... no (pkg-config file not found)
 Trying to generate pkg-config file for ufc-1... failed
[snip]

Warning: Unknown dependency package: ufc-1
*** Unable to import UFC. Install latest UFC
$

I guess you have the UFC module in $PYTHONPATH but not the ufc-1.pc file
in $PKG_CONFIG_PATH.

If I do set the paths to UFC correctly but remove the libxml2-dev Debian
package I get a similar message as you:

 Checking for libxml-2.0... no (pkg-config file not found)
 Trying to generate pkg-config file for libxml-2.0... failed
Resolving compiler... done
Warning: Unknown dependency package: libxml-2.0
Enabling compilation of Python wrappers
scons: done reading SConscript files.
scons: *** No targets specified and no Default() targets found.  Stop.
---------------------------------------------------------
Compilation of DOLFIN finished. Now run

I guess we should change the warning about the unknown dependency package
into an error and exit. I'll do that now.
