CFLAGS=-fPIC ./configure
make CFLAGS=-fPIC LDFLAGS=fPIC install

This installed libunwind without any issues. And I could compile google profiler with this libunwind. I am trying it out with our project. I will update you shortly after profiling.

Thankx once again for the extraordinary help Arun and David.

Hi David and Arun,

I downloaded the snap shot and tried compiling in my 64 bit linux with the following.

make (tried this. But got an error).
 make LDFLAGS="-fPIC" (even with this the same error. Details are pasted below.).
