libmap unclear

[jb_daefo]

I have a few lines in libmap.conf which try to fix non-loading chromium. That fails, the port still wants a nonstandard libfontconfig.so.1 location, so I added that to libmap.conf, which did nothing, so I commented out the chromium block. This was all in a rush, so I may be mistelling or unclear on what transpired, but differing versions of libstdc++.so.6 IIRC gcc46 vs gcc49 OR some other line within the block for
chromium is/was needed for all system binaries! As to restore a libmap.conf from elsewhere in a backup subdirectory, I had to for a few harrowing moments use
/rescue/cp /rescue/ls etc...
If the situation was as I recall it, to reiterate.

The reason I am posting here is because I have no time to fiddle with it for the
next few years, maybe someday someone will write a more definitive guide to
using libmap.conf and/or how to fix chromium that is skewed that way and/or
more functionality to ldd to make libmap.conf less relevant, by manual placing
in /usr/local/lib/compat if that is even feasible... just clueless so far, also *not
important* so much as someone may chime in with something I should know and
do not.
