You don't give many clues as to what might be going wrong. Do you set
the PKG_CONFIG_PATH when you configure iaxclient? Where do iaxclient's
dependencies get installed? /usr/local? Do you have different versions
of speex, portaudio, etc. installed in /usr/lib?

You should know that this whole exercise of building a shared object
with no shared object dependencies is much like swimming upstream. The
build tools are all geared towards either building things statically
or building things shared, but not mixing the two in this way. I am
curious as to why it is so important to avoid these dynamic link
dependencies -- especially on linux?
