Short answer :
FFTW uses only SSE. Please stay with standard features if you recompile it on your own. See docs contained in their downloadable GNU package (version 3.2.2.1 from fftw.org). No benefit from compiling with SSE3, rather this could break compatibility of AP results with other platforms.
SSE3 code is used only from inside AstroPulse. And gcc 4.2.1 (comes with FreeBSD7.2 64bit) does support building SSE3 code.
Static linkage i tried, but gcc gave me what you got, because of problems beyond. Maybe i should update to a newer version of gcc and make a new build, which will then hopefully go "full speed" and use less shared libs.

There's a guide over at freebsd.org: http://www.freebsd.org/doc/en/articles/custom-gcc/article.html
Doesn't seem too complicated to follow but the risk of creating incompatible results is ofc reason enough to stay away... thanks for the answer. I was just curious and try to learn by picking up bits and pieces here and there.

Hi PP, thank you, my Xeon is computing first unit ;D there are no more units now. I will report further.
Which file in Astropulse contains the line where I can read how much work is already computed?
pp:
You're welcome. Doesn't your Boinc manager show you how far the wu has progressed? I know the 6.9.x version had some trouble with this but earlier and later versions should work correctly in that respect.
zvonas:
No, I am running command-line client. In seti@home enhanced there was file named state.sah in slot directory and it contained frac_done line with some number - e.g. 0.4266, = 42.66 %
