First, 2.95 is old...  You'll get better milage out of newer 
compilers...

Second -frepo didn't work with apple provided g++ compiler for a while, 
so mixing the two will lead to heartache.  Second, using -frepo across 
a .a file need not work so well.

Running with -v, and seeing if collect2 runs will tell you if -repo is 
going to work at all.  If it does, it will, if not, it won't.

From there, you can examine the .rpo files and see if and where the 
missing symbols are able to be defined.  If you flip them by hand 
(useful in the case collect2 isn't going to work, or you don't want to 
let the linker see the object files by hiding them in a .a file), you 
should be able to instantiate all the missing symbols.  Kinda gross, 
but you asked.

I'd say, remove -frepo, remove -fno-implicit-templates, use gcc-3.1, or 
gcc-3.3 from apple, and presto, everything should just work.
