The last time a rebuild of (almost) everything was required was when the C++ ABI changed, with the associated bump of SONAME from libstdc++.so.5 (provided with GCC 3.3 and earlier) to libstdc++.so.6 (provided with GCC 3.4 and later). So you were close, but the major change happened with 3.4, not 3.3 ;). Some old binary software still requires libstdc++.so.5, which can still be installed from sys-libs/libstdc++-v3, which actually builds part of GCC 3.3.6 to get the libstdc++.so.5 to install. - -- Jonathan Callen -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCgAGBQJUZYqGAAoJELHSF2kinlg4sTYP/A1f89WjzUi4yqM+ob9XCovU sVbgWS2hW2UL8wDeRuqbQoF6fAtVBLx5J2+akR+TOJN7BQ1fORBOkfOtcdw1vn8l 8YZ8LVKSPvB9+EQimuiLGYfWSoVFOwsoc6zL6htFHQhdqb4+O7ceJ1Iqn/PcHxU2 srUnR/Fh5rD1dUch5borZ2Px/g9ivr/91PvTulPIR2940dhregpS+7PyvaZGl2FF Ov8f9ewdf5rDVBZxwzPHpF87dQIOl+0Bxkvr3M1a/yXKxJR38fqSuFI64hlpfln1 uadiytz1WpwEOwK12a36YsnVtenMJFwn2ySnyRGZRL1lltkzHX+RNqLv58lDO4KY jUEx9jBrNfN683X2DKFOkeshlhLHGchnahPTZkW5Vcs7NjTnmbI7V9p5oJkjf59u TftGNb1PTCA9eZYcxpujwkFy+0jiLagbukfxyUqLFMhEt3kTiSBeUVMpCHlBDC3Z XLCGpdj0lX9P6hUGzkz2S8nI/iX7z7MZx/EDtLRo61sE9r7zOQUTYgOISgm2cYge d8nvNguJ3iHESXTeAOu/C+nH+shPelaT62sF7rKUWc0GyudOXmttN9WiSNgN/1nI uuWPcOiP/1hGGl/qkJNrOId+j74lP4ljW3MHjFG+vsVUM+kBHzUFD8gIls2Q6qa4 beea0YeRqT+GLg1XGUvC =5KgF -----END PGP SIGNATURE-----
