hi -

can you try to apply this patch, make clean, make, and tell me what happens: http://timetobleed.com/files/memprof-fix.patch

there is a bug/miscommunication issue in libelf with the function that is giving you problems. so let's try a simple fix first, and if this fails we'll do more digging.

How to apply this patch? (Ubuntu 9.10)

$ ruby -e "require 'memprof'"
ruby: symbol lookup error: /usr/local/ruby/lib/ruby/gems/1.8/gems/memprof-0.1.2/lib/memprof.so: undefined symbol: elf_getshdrstrndx

[tmm1]

this was fixed by bundling our own version of libdwarf and libelf
