Anyway

Just curious why setting LD_PRELOAD for a single file complains
about BINDIR
That's almost definitely from your erlang entry in LD_PRELOAD.
As others have mentioned, setting LD_PRELOAD in your shell is
massively deprecated - you can and will get weird results.
When you're building your utility/app/whatever, use
LDFLAGS=-R/path/to/libs:/path/to/other/libs -L/path/to/libs
-L/path/to/other/libs
that way the binaries will have the right search path baked into them
at compile time, rather than you needing to hack around them with
LD_PRELOAD afterwards.
As an aside if anyone can recommend good source/tutorial on linking
/ compiling in c I would be very grateful.
I recommend bookmarking this collection:
http://docs.sun.com/app/docs/coll/45.27?l=en
OpenSolaris Software Developer Collection
and then having a read through the Linker and Libraries Guide
(http://docs.sun.com/app/docs/doc/819-0690?l=en).
That will make you think of a lot of questions, soask.
