mecab-java linker error

[mattes.angelus@…]

trying to run java programm with macports mecab-java throws an exception, since macports libiconv (macports mecab depends on it) conflicts with yosemites system libiconv:

dyld: Symbol not found: _iconv
  Referenced from: /usr/lib/libmecabra.dylib
  Expected in: /opt/local/lib//libiconv.2.dylib
 in /usr/lib/libmecabra.dylib 

This bug seems related to this: #43698
When i try to use system libiconv (rename macports libiconv libs) the java class throws this error:

java.lang.UnsatisfiedLinkError: /opt/local/lib/libmecab-java.dylib:  Library not loaded: /opt/local/lib/libiconv.2.dylib   Referenced from: /opt/local/lib//libmecab.2.dylib   Reason: Incompatible library version: libmecab.2.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

Why is /usr/lib/libmecabra.dylib (which, based on its location in /usr/lib, appears to be provided by the operating system) referencing anything in /opt/local (which is MacPorts territory)? Do you perhaps have the DYLD_LIBRARY_PATH environment variable set? If so, unset it.

first thank you for the fast reply and formating my text
yes, i have to set the DYLD_LIBRARY_PATH to /opt/local/lib in my java ide otherwise i have to use

System.load("/opt/local/lib/libmecab-java.dylib");

instead of

System.loadLibrary("mecab-java");

and this linker error is thrown:

i guess, without DYLD_LIBRARY_PATH it's missing the corresponding libs in /opt/local/lib.
with using DYLD_LIBRARY_PATH it takes the corresponding libs from /opt/local/lib. but there is no mecabra.dylib, so it searchs for it in java.library.path (where /usr/lib/ is in). and so the error occurs... but that's just my guess
