[x264-devel] removing (old) versions of x264

[Matyas]

This is a completely newbie question.

I am compiling and installing x264 from git.  I say make install as root
as the last command:

# make install
install -d /usr/local/bin /usr/local/include
install -d /usr/local/lib /usr/local/lib/pkgconfig
install -m 644 x264.h /usr/local/include
install -m 644 libx264.a /usr/local/lib
install -m 644 x264.pc /usr/local/lib/pkgconfig
install x264 /usr/local/bin
ranlib /usr/local/lib/libx264.a

Does this remove (overwrite) old versions of the x264?  There are indications
that I have old x264 laying around my system, since mencoder picks up that
old version:
Well? > /usr/local/bin/x264 --version
x264 0.68.1189 9d0b5e9
Well? > strings test.avi | grep x264
x264 - core 65 r1073 6a4a9be...

Thanks.
