You are mixing libraries (and/or object files) compiled by different 
versions of gcc (for example gcc-2.7.2.1 and gcc-2.8.1). It is OK to 
do this with C but NOT with C++. There were even problems using
libraries built with gcc-2.8.0 with gcc-2.8.1 (warning: there will be 
similar problems with upcomming egcs-1.1)

So please either get all C++ libraries built with the same compiler 
version as You are using or rebuild them from sources.

Symbols __eh_pc and __throw are defined in libgcc.a which is 
specific to compiler version.
