You're absolutely right. "-ljack" and "-lrt" are still there and there 
is no "-framework jack".

Checking the *.pc files gives the following:

I then edited the jack.pc file using pico as follows:

did a "make clean" then "make". This...only returns the same error 
message of undefined jack symbols:

It looks like the problem is rather at "ld: warning prebinding disabled 
because dependent library: /usr/local/lib/libfluidsynth.1.dylib is not 
prebound"

Could the failure to prebind "libfluidsynth" be due to the following 
diagnostic messages from the build file?:

I checked out the LD_SEG_ADDR_TABLE environment variable:

I'm looking into how I could insert the -dylib_install_name 
"/usr/local/lib/libfluidsynth.1.dylib" into the segment address table 
(defined by the environmental variable LD_SEG_ADDR_TABLE) found in 
"/sw/var/lib/fink/prebound/seg_addr_table". Firstly, 
"/usr/local/lib/libfluidsynth.1.dylib" does not exist yet. It is 
presently in the hidden directory "fluidsynth-1.0.3/src/.libs". It is, 
in fact, a symbolic link to the Mach-O dynamically linked shared 
library "libfluidsynth.1.0.0.dylib" which itself is also in the .libs 
directory. So can I just simply "mv 
fluidsynth-1.0.3/src/.libs/libfluidsynth.1.dylib  
/sw/lib/libfluidsynth.1.dylib" ? Then, run "/sw/bin/seg_addr -update -o 
 /sw/var/lib/fink/prebound/seg_addr_table" ??? (I don't want to screw 
up any OS parameters.) If this is okay, then I could re-make.

In addition, it looks like MidiShare is also not linked properly (see 
ranlib command above). This may also lead to problems in building 
fluidsynth??

Many thanks.
