如何从iOS框架中剥离或重命名符号？

Question

I need to fix a bug in an underlying iOS framework that is linked to route-me and when i include the new code I'm getting

ld: duplicate symbol _OBJC_METACLASS_$_RMProjection in frameworks/blah.framework/blah(RMProjection.o) and 

Is there a way to stip the symbol from the blah.framework and use my compiled code instead? I'm aware of: strip -s <symbol file> -u <library> but can't get it to work

Also tried doing a find and replace

perl -n -p -e 's/RMProjection/XRMProjection/g' < frameworks/blah.framework/blah.bak > frameworks/blah.framework/blah

in the linked binary, which results in this error:

ld: in frameworks/blah.framework/blah, file is universal but does not contain a(n) i386 slice for architecture i386

Thanks
