The .dyld is created assuming it will only be used from within a
framework. As a result the library paths that get imbedded in isql and
the dyld itself don't work appropriately with DYLD_LIBRARY_PATH. In
fact the code looks for resources within the framework, so even if the
dynamic linker was able to resolve all the symbols it still wouldn't
work correctly. Instead of DYLD_LIBRARY_PATH try using
DYLD_FRAMEWORK_PATH and point it at
$HOME/projects/firebird-1.5.2.4731/gen/firebird . Of course you need
to make sure the framework is actually there as well :-)
