Fedora Core 2 - a patch and problems

I am attempting to build the BBC on Fedora. So far I've found one critical
patch below :-)

The problem now is with compile variables. I want to make sure that things
are set right before diving into a fix.

The project is checked out to /home/daves/lnxbbc/gar
build_prefix is set to /home/daves/lnxbbc/build
main_DESTDIR is set to /home/daves/lnxbbc/maindestdir
all other variables are default

Several packages are failing to install in the right place. gdbm is trying
to install relative to main_prefix (=/), instead of main_DESTDIR. The make
call for install is passing in the value of main_prefix for the "prefix"
variable (which is passed into INSTALL_OVERRIDE_DIRS)

Have I set the variables correctly?
Shouldn't INSTALL_OVERRIDE_DIRS = prefix cause the make file to set prefix
to /home/daves/lnxbbc/maindestdir?
Does anyone have the Fedora build working?

I've seen python and modutils install to someting like
$(build_prefix)/$(build_prefix)/lib. That comes next. Threads don't install
right either. Much of the rest appears ok.

I am building against blotto, though the research branch failed at the same
place. No chroot. Athlon.
