OK, I waddled back to my system, and tried to figure out the problem 
with the Makefile generated by Configure.  'make' doesn't make it 
easy :-}

First, the 'separator' error arises becase the library name is 
terminated with a ';', which causes the system some indigestion.  Cf. 
the line below marked with <<<<<.

Second, you don't appear to need "-I/usr/local/include" for Mac OS X, at 
least in versions 10.2 and later.  I'll check into that further, but as 
it is (on 10.2.2 with all tools updates installed), the compiler grouses 
about having that directory specified.

Finally (or, third), 'ld' grouses about the argument to "-i".  The 
complaint is:

   /usr/bin/ld: -i argument: nstall_name must have a ':' between its 
symbol names

The line in question is

/usr/bin/ld  -o libpari-2.2.2.dylib -install_name 
/usr/local/lib/libpari-2.2.2.dylib -compatibility_version 2.2 
-current_version 2.2.5 kernel.o mp.o alglin1.o alglin2.o arith1.o 
arith2.o base1.o base2.o base3.o base4.o base5.o bibli1.o bibli2.o 
buch1.o buch2.o buch3.o buch4.o galconj.o gen1.o gen2.o gen3.o 
ifactor1.o perm.o polarit1.o polarit2.o polarit3.o rootpol.o subcyclo.o 
subgroup.o trans1.o trans2.o trans3.o aprcl.o elliptic.o galois.o 
kummer.o mpqs.o nffactor.o stark.o subfield.o thue.o anal.o compat.o 
errmsg.o es.o helpmsg.o init.o sumiter.o mpinl.o

I'm not at all sure what's up here.  Is '-install_name' a GNU thing?  I 
see that 'libtool' has an argument by that name.  At this point, though, 
you get beyond my understanding.

To summarize: removing the ';' above lets me run Configure and 
successfully run "make gp".  The 'ld' problem causes the build to break 
prior to actually building the library.

Justin
