  No problems. I am doing a test build and package adaptation to
know ahead of time most issues that will need to be solved.

  Well, until last sunday I was running Mandriva cooker at home, so, I
am used to things breaking, badly :-)

  Note accurate :-) What happens is basically that sagemath has
a interface to handle signals, etc, and have a place for a static
string that should describe an error, and it wants to wrap "NTL
print string to stderr and call abort" logic, what makes sense
when NTL is a library it is linked to. The sagemath patch also
adds an extra context pointer to the callback.

  Ok. I just got home, built your cliquer package, but no luck:

gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC
-fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
-mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC
-I/usr/include/python2.7 -c sage/graphs/cliquer.c -o
build/temp.linux-x86_64-2.7/sage/graphs/cliquer.o -w
In file included from /usr/include/cliquer/graph.h:5:0,
                 from sage/graphs/cliquer.c:235:
/usr/include/cliquer/set.h:16:18: fatal error: misc.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1

cliquer probably would need this patch, otherwise unsure how
to handle it:
and there is another header file in the SOURCES dir.

  I also packaged cliquer 1.2 and not updated it, and 1.2 happens
to be the one used at least by sagemath 4.8.

  This is another case we should push for upstream adding
support to the desired interface, not necessarily verbatim
patch and adding new sage_xyz symbols.
