In fact most of the changes will probably involve a one line addition.
As an example, galculator-1.3.4-2.fc12.src.rpm was found to be failing
because libm is used but not explicitly linked.
RPM build errors:
/usr/bin/ld.bfd: math_functions.o: undefined reference to symbol 'sin@@GLIBC_2.0'
/usr/bin/ld.bfd: note: 'sin@@GLIBC_2.0' is defined in DSO /lib/libm.so.6 so try
adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation
The following would fix this and allow the package to build.

There's an example at the bottom of the page :
demonstrating what a failed build message would look like,
and how to go about fixing the issue.
