Forest will be Ok, too :) It seems, that root of gcc44 dependency is
x264, but I'm not sure, that it is ONLY root.

[many bad words skipped]. WHY, OH, WHY libgcc is not used as
static library?! It is only implementation of some intrinsics, am I right?
And now gcc4 is DEPRECATED, so I need to rebuild ANY port,
which is depend on it (via some wired paths, whose I cannot not easily
track) to update it to gcc45?! Ouch.
How could I determine which ports are directly lined with libgcc from
gcc44? ldd? But x264 itself (yes, it is built with GCC44 option) is
not linked to libgcc:
blob# ldd /usr/local/bin/x264
/usr/local/bin/x264:
libgpac.so.1 => /usr/local/lib/libgpac.so.1 (0x800812000)
libz.so.5 => /lib/libz.so.5 (0x800be3000)
libm.so.5 => /lib/libm.so.5 (0x800cf8000)
libthr.so.3 => /lib/libthr.so.3 (0x800e18000)
libc.so.7 => /lib/libc.so.7 (0x800f31000)
libssl.so.6 => /usr/lib/libssl.so.6 (0x801172000)
libcrypto.so.6 => /lib/libcrypto.so.6 (0x8012c5000)
libjpeg.so.11 => /usr/local/lib/libjpeg.so.11 (0x801565000)
libpng.so.6 => /usr/local/lib/libpng.so.6 (0x80169b000)
I could check all binaries and shared libs, of course, (find, xargs,
ldd), but it is not what I call "user friendly" :(
