+# Debian and Red Hat, and perhaps other vendors, provide both runtime and
+# development packages for some libraries. The runtime packages contain shared
+# libraries with version information in their names (e.g., libgdbm.so.1.7.3);
+# the development packages supplement this with versionless shared libraries
+# (e.g., libgdbm.so).
+#
+# If you want to link against such a library, you must install the development
+# version of the package.

-# If you wish to use something other than 'gcc' for your compiler,
-# you should specify it on the Configure command line. To use

+# libgdbmg1 (non-development version of GNU libc 2-linked GDBM library)
+# libgdbmg1-dev (development version of GNU libc 2-linked GDBM library)
+# So make sure that for any libraries you wish to link Perl with under
+# Debian or Red Hat you have the -dev packages installed.
+#
+# Some operating systems (e.g., Solaris 2.6) will link to a versioned shared
+# library implicitly. For example, on Solaris, `ld foo.o -lgdbm' will find an
+# appropriate version of libgdbm, if one is available; Linux, however, doesn't
