1. (The esiest) don't use -ftracer That's what I do now.
2. (A little bit more difficult) use my version of CLN, you can get it from git://ffmssmsc.jinr.ru:443/varg/cln.git WARNING: it's binary incompatible with original version (the API is the same, though). Since Gentoo is a source based distribution, this should work. I'll suggest it on Gentoo bug tracker. But, this might not be easy or even necessary as this is really a very minor issue. Gentoo build scripts can easily filter out -ftracer flag.
3. (Hard) convince CLN developers to wipe out CL_REQUIRE/CL_PROVIDE stuff. That's where I went wrong. I thought (mistakenly it appears) CLN is also developed by this group. I'll give it a try with CLN developers anyway.
Thanks again for the prompt response. -- Sam PS: GiNaC is a very cool piece of software. I stumbled on to it by accident, but I'm glad I did :)
