automake problem with multiple "-rpath"

[aotto]

Hi,

problem: I want to start a software WITHOUT the environment is set - 
this include LD_LIBRARY_PATH
(HELP: the '...' down in the text are from me to shorten the output)

> ./cct

couldn't load file ".../libtclreadline.so": libreadline.so.4.0: cannot 
open shared object file: No such file or directory

analyze:

> ls -al .../libtclreadline.so
lrwxrwxrwx 1 dev1usr users 23 10. Mai 09:39 .../libtclreadline.so -> 
libtclreadline-3.0.0.so

The file is available BUT point with as SOFT-LINK to LOCAL file

-> seems that -rpath .  (local directory is NOT available)
-> seems that WITHOUT local directory in LD_LIBRARY_PATH the softlink 
(from automake) seems NOT to work

---------------------------------
solution #1, setup LD_LIBRARY_PATH after software cct has started

adding LD_LIBRARY_PATH after cct was started does NOT help because 
'ld.so' seems to use the LD_LIBRARY_PATH before
cct was started.

-> HOW I tell 'ld.so' to accept a new LD_LIBRARY_PATH after start from cct ?

-----------------------------
stepping deeper I start to analyze the build of libtclreadline, an 
automake software

I install the "automake" software tclreadline with the following build-plan:

#1 tclreadline source build and install into staging-area
#2 staging-area tested and verified, finally copied into destination-area

with: staging-area != destination-area

problem: The '-rpath' from the 'staging-area' does not fit into the 
'destination-area'

TRY for solution:

#1 add line 'libtclreadline_la_LDFLAGS = -release 
$(MAJOR).$(MINOR).$(PATCHLEVEL) -rpath .../lib' to Makefile.am

# output

/bin/sh ./libtool  --tag=CC   --mode=link gcc -m32 -O2  -g -O2 -release 
3.0.0 -rpath .../linuxi386/lib  -o libtclreadline.la -rpath 
.../var/pkg/install/TclRl_3_0/lib tclreadline.lo  -lncurses  -L... 
-lreadline

libtool: warning: ignoring multiple '-rpath's for a libtool library

staging area : -rpath .../var/pkg/install/TclRl_3_0/lib
destination-area : -rpath .../linuxi386/lib

#1 As you see NO multiple -rpath are NOT allowed
#2 Same for '-rpath .' local directory is not allowed at all !!

conclusion:

#1 I can NOT set the LD_LIBRARY_PATH after start (preferred solution)
#2 I can NOT set the right -rpath to the automake created library

question

#1 what to do?
#1 tclreadline is just an example other automake software likely have 
the same problem.
   I prefer NO solution where I have to modify ALL Makefile.am files 
because of the
   -rpath problem.
