I noticed that 2.2.5->2.2.6 seemed to take away building the shared 
library on Mac OS X.  Is that easy to repair?

I did the above in both the pari and gp2c directories, and the build 
worked in both cases, but for 'gp2c', the "make check" failed (as 
before: '-o' was attempted as a command).  It appears that the 
PARI_MODULE_BUILD macro is the culprit, FWIW.

Also, there is no gp-dyn after 'make bench' in 'pari'.

For 'pari', I added two darwin entries:
in the '$osname-$arch' case statement:
  darwin-*)soname=dyld ; sodest= ;DLSUFFIX=dylib ;;
in the '$osname' case statement:
      darwin)  DLLD=/usr/bin/gcc ;;
Something else is needed, though.  Not sure what, yet.  At least, when 
I cobbled together a libtool line, I got a .dylib.  Not sure yet 
whether it works, though.

Moved and seconded :-}.
