Same named binaries in $PATH && build error

[Datasmurf]

Hello,

while building www/chromium on 

FreeBSD monolith03.lan 9.2-RELEASE-p5 

devel/binutils installs those binaries

        /usr/local/bin/ar
        /usr/local/bin/as
        /usr/local/bin/c++filt
        /usr/local/bin/gprof
        /usr/local/bin/ld
        /usr/local/bin/ld.bfd
        /usr/local/bin/ld.gold
        /usr/local/bin/nm
        /usr/local/bin/objcopy
        /usr/local/bin/objdump
        /usr/local/bin/ranlib
        /usr/local/bin/readelf
        /usr/local/bin/size
        /usr/local/bin/strings
        /usr/local/bin/strip

in /usr/bin are ar,as,c++filt etc. are the system binutils.

audio/alsa-lib

would not find libphyton2.7 with system /usr/bin/ld after

after mv /usr/bin/ld /usr/bin/ld.bsd

The Port audio/alsa-lib continued to build without a error.

I wonder why there are 2 binaries on the system with the same name?
Why arent the system binutils are not renamed after installation of
port devel/binutils or those are named gld and gar etc.

Doesn't make much sense to me, and i am confused. 

What does freebsd-questions@ think?

best regards
