Now I got it working with CUPS by changing the default print service at
compile time. The problem was the quoting. The current code

-----------------------------------------------------------------------
#ifndef DEFAULT_PRINT_SERVICE
#define DEFAULT_PRINT_SERVICE   "lpsched"
#endif

...

char *scheme = DEFAULT_PRINT_SERVICE;
-----------------------------------------------------------------------

requires from the user to supply also the quotes. So in the spec file I
had to do

-----------------------------------------------------------------------
export CFLAGS="$CFLAGS -DDEFAULT_PRINT_SERVICE=\\\"ipp\\\""
%configure --without-apache
%make
-----------------------------------------------------------------------

Note the quoted quotes in the first line. This I did not do in the first
place and therefore it broke.

But please still supply the documentation to configure PAPI at run time.
Also a possibility to define the compile time default by the configure
script, both by spooler auto discovery and also by command line option
would be great.

Note also that on the linker call(s) for the Ruby bindings the

-L$RPM_BUILD_DIR/papi/source/libpapi-dynamic/.libs

is missing. So I had to put

-----------------------------------------------------------------------
export LDFLAGS="$LDFLAGS -L$RPM_BUILD_DIR/papi/source/libpapi-dynamic/.libs"
-----------------------------------------------------------------------

before the "%configure" in the spec file.
