YAQ on /usr/bin/ld

[Labitt, Bruce]

You all must be tired of me by now, but I've got YAQ (yet another
question) on ld.  (At least I have been bringing up new topics to the
list, and they are linux related.)  

I have been trying to compile octave for a while and am stumbling on an
odd failure (I think) with ld.

About 20 minutes into the make I get a failure which I believe is
related to ld.  The  two lines before the failure are:

g++ -c  -fPIC -I. -I.. -I../liboctave -I../src -I../libcruft/misc
-DHAVE_CONFIG_H -Wall -W -Wshadow -Wold-style-cast -g -O2
./DLD-FUNCTIONS/regexp.cc -o pic/regexp.o
g++ -shared -o regexp.oct pic/regexp.o -L../libcruft -lcruft
-L../liboctave -loctave -L. -loctinterp        -llapack -lblas -lfftw3
-lreadline  -lncurses -ldl -lz -lm  -L/lib64 -L/usr/lib64
-L/usr/lib/gcc/x86_64-redhat-linux/4.1.2
-L/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64
-L/lib/../lib64 -L/usr/lib/../lib64 -lz -lgfortranbegin -lgfortran -lm
-lpcre

/usr/bin/ld: skipping incompatible /usr/lib/libpcre.so when searching
for -lpcre
/usr/bin/ld: skipping incompatible /usr/lib/libpcre.a when searching for
-lpcre
/usr/bin/ld: cannot find -lpcre
collect2: ld returned 1 exit status
make[2]: *** [regexp.oct] Error 1
make[2]: Leaving directory `/home/BDLabitt/octave-3.0.1/src'
make[1]: *** [src] Error 2
make[1]: Leaving directory `/home/BDLabitt/octave-3.0.1'
make: *** [all] Error 2

libpcre.so and libpcre.a are in /lib64.  Why doesn't ld find it?,
especially since I did pass the argument -L/lib64 ?

Or am I looking in the wrong place?

For giggles I tried /usr/bin/ld -L/lib64 -lpcre and get
/usr/bin/ld: skipping incompatible /usr/lib/libpcre.so when searching
for -lpcre
/usr/bin/ld: skipping incompatible /usr/lib/libpcre.a when searching for
-lpcre
/usr/bin/ld: cannot find -lpcre

My old OS SL5.1 did not have this problem...  

I do have both 32 & 64 bit versions of lpcre installed.  Parts of kde
seem to depend on it, otherwise I'd get rid of it.  32 bit lpcre is in
/lib, 64 bit pcre is in /lib64.
