I built readline-6.2 from source and got passed linking 'postgres'
executable.  Progress!  now chasing down libperl

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith
-Wdeclaration-after-statement -Wendif-labels -Wformat-security
-fno-strict-aliasing -fwrapv -fpic -shared -o plperl.so plperl.o SPI.o
Util.o -L../../../src/port -Wl,--as-needed
-Wl,-rpath,'/usr/lib/perl/5.10/CORE',--enable-new-dtags
-fstack-protector -L/usr/local/lib  -L/usr/lib/perl/5.10/CORE -lperl
-ldl -lm -lpthread -lc -lcrypt
/usr/bin/ld: cannot find -lperl
collect2: ld returned 1 exit status

I had to make a simlink 'ln -s /usr/lib/libperl.so.5.10
/usr/lib/libperl.so' which I thought was supposed to happen automagically...

BUT
make[1]: Leaving directory `/home/rob/tools/postgresql-9.1.1/config'
All of PostgreSQL successfully made. Ready to install.
PostgreSQL installation complete.

Thank you Tom for the readline tip.  Sort of thing that would take me
forever to track down.
