Hi - We wanted to install glimpse on a maching running Mac OS X.
 Just so you know, it gives errors which are corrected by downloading
 the following libraries not present on the Max OS X flavor of UNIX
 (Darwin) - dlfcn.h, libdl.dylib and libdl.a.
 
 On typing "make" after ./configure the following error is generated:
 
 [..]
 gcc -c -I../index -I../agrep -I../libtemplate/include  io.c
 io.c:7: header file 'dlfcn.h' not found
 cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode
 make[1]: *** [io.o] Error 1
 make: *** [build-sub] Error 2
 
 Copying the dlfcn.h in /usr/local/perl-5.8.0/os2/dlfcn.h to /usr/lib fixed it.
 Then we got the error:
 
 [..]
 gcc  -L../lib -o ../bin/buildcast buildcast.o region.o dir.o io.o build_in.o filetype.o simpletest.o getword.o memlook.o lib.o partition.o       -lagrep -ldl 
 ld: can't locate file for: -ldl
 make[1]: *** [notsbuildcast] Error 1
 make: *** [build-sub] Error 2
 
 The libdl.dylib and libdl.a libraries can be downloaded as a package from
 http://star.mfn.unipmn.it/osxgnu/Libraries/dlcompat-10505X.pkg.sit
 Double-click on the icon and the libraries will install in /usr/local/lib
 Glimpse then installs and runs without incident.
 
 Hope this is useful.
