Maybe apple-gcc is different than fsf-gcc, but for me it looks like:
*) gcc does not detect being moved, because it does not pass any
"-iprefix" to cc1.
*) there's no "-I" on original gcc-commandline.
How exactly is that gcc configured (should be part of "gcc -v" output),
and what commandline params did you use here ?

Resulting path list good, but the nonexistent "/Library/Gentoo/include"
seems to come from "--with-local-prefix=/Library/Gentoo" ?

Stuff becomes fuzzy when gcc erroneously detects being moved :-(
And it's my daily job to shed light on fuzzy things :-)

Exactly, dropping CPPFLAGS from profile.bashrc is what I intended,
thanks!

PS: I've not finished playing with LDFLAGS/LD_RUN_PATH/LD_LIBRARY_PATH
in profile.bashrc, but I'm unsure yet how to do it right.
Can you 'emerge ncurses' with "-Wl,-R" in LDFLAGS ?
