+# Debian and Red Hat, and perhaps other vendors, provide both runtime and

+# 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

+# These packages use a -dev naming convention in both Debian and Red Hat:
+# 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.
