(Sylvain, please also post your emerge --info output, which will include everything that you have set up in the /etc/make.conf, but also a lot of informative info wrt your system's toolchain).
Maybe you should modify CFLAGS in your /etc/make.conf to CFLAGS="-O2 -march=athlon-xp -pipe -msse" and the same for CXXFLAGS Consult the /usr/share/portage/config/make.conf.example before applying these changes

-msse ???????? you must kid Alfredo.......... i will not set such a flag in there, because i will soon change of CPU, and you must take in that for users... sorry same player shoot again !
UFO-AI seems to need sse (at least getting that from the sentence you put. gcc, with -march=i686 does not provide sse, it is just a PentiumPro that, as you know, lack sse instruction set The code that is compiled with such an option can run on athlon-xp but do not use/recognize sse You can say -march=native or -march=athlon-xp to inform gcc about the instruction set it can use in the generated code When / if you change your cpu, and your cpu does not have the instruction set that is present in the athlon-xp, you have to rebuild everything. At least you could try to change the make.conf only for the build of ufo-ai If the error remain the same, try also adding -msse (I don't think that is a winner, but you could try)
ok, it builds with -msse in CFLAGS
