'sudo' as SU_CMD on Solaris w/sunfreeware gcc3.4.6

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

I'm using gcc3.4.6 from sunfreeware.com, so some things are linked
against /usr/local/lib/lib*.  They run fine as an ordinary user
(LD_LIBRARY_PATH=/usr/local/lib:/usr/pkg/lib) but failed when becoming
root.  This is particularly true of tools like "gmake" required to build
other packages.

I'd installed 'sudo' from pkgsrc-2008Q1 and was using it for my "SU_CMD"
in "mk.conf", the problem only showed up when I attempted to install
something that used these extra tools, particularly 'gmake', during
installation.

Since the recent versions of 'sudo' reset the environment to a minimal
set, "LD_LIBRARY_PATH" was not included.  When I ran 'ldd' on the
offending programs as my regular user, all was well.  When I ran 'ldd'
as root using 'sudo', libraries previously shown to be in /usr/local/lib/
were listed as "file not found".

The solution was to be sure my sudoers file contained something like:

  Defaults env_keep+="FOO BAR BAZ QUX LD_LIBRARY_PATH"

to make sure that LD_LIBRARY_PATH is preserved when using 'sudo' to
become root.

Hope this helps other pkgsrc/Solaris users.
