I had some trouble compiling GnuCash 1.6.6 from the source RPM for "vanilla"
Red Hat 7.2,
http://www.gnucash.org/pub/gnucash/redhat-7.x/SRPMS/gnucash-1.6.6-1.src.rpm.
It requires a bunch of *-devel RPMs, such as g-wrap-devel, that aren't
necessarily installed by a normal Red Hat installation.  That caused the
"configure" step to fail for lack of one file or another.  Tracing through
config.log to figure out what was missing and what RPM to install was a bit
tedious.

Here's a new gnucash.spec with added "Buildrequires" directives that say what
packages are needed to build from source.  If you build GnuCash from a source
RPM with this spec, rpm will tell you right up front what packages you are
missing.  You should be able to install gnucash-1.6.6-1.src.rpm, replace
gnucash.spec, and use rpmbuild to build the package.

The other thing that this .spec does is use rpm's (badly documented) "--with"
option to decide whether to build the Postgres back end.  If you run the
command
    rpmbuild --with postgres -bb gnucash.spec
the result will be a file named gnucash-postgres-1.6.6-2.i386.rpm, containing
a GnuCash with Postgres support.  Running either of
    rpmbuild -bb gnucash.spec
    rpmbuild --without postgres -bb gnucash.spec
creates gnucash-1.6.6-2.i386.rpm and leaves Postgres out.  I set up the spec
file to require Posgres version 7.1.3 because that's what came with Red Hat
7.2 -- I suppose earlier versions would work, but I don't know how low to go.

I haven't tried this on any other of the Red Hat variants, or any other
RPM-based distributions.  If you try it, let me know how it goes.

Finally, I have a .src.rpm and two .i386.rpm files build from this spec.  Can
I contribute them?

%description
GnuCash is a personal finance manager. A check-book like
register GUI allows you to enter and track bank accounts,
stocks, income and even currency trades. The interface is
designed to be simple and easy to use, but is backed with
double-entry accounting principles to ensure balanced books.
%if "%{_with_postgres}" == "--with-postgres"
This package supports the use of Postgres to store account data.
See %{_docdir}/%{name}-%{version}/README.postgres for more information.
