spec file issues in 1.5.5

I'm trying to build the RPM on CentOS 5.1 and encountered these issues:

The spec file refers to the tarball by the old version, 1.5.4.

The spec file appends a revision ("_1") to the tarball name and main 
directory that's not in fact there.

There should be a buildprereq on the ghostscript package or its binary.

/usr/man/man1/doxywizard.1.gz is missing from %files.

After fixing these I was able to get the package to build and install.

I don't see a rule in the Makefile to convert the .spec.in file to the 
.spec file. The man page issue appears fixed in the .spec.in but the other 
issues appear to still be there.
