27 | # the development packages supplement this with versionless shared libraries | |
28 | # (e.g., libgdbm.so). | |
29 | # | |
30 | # If you want to link against such a library, you must install the development | |
31 | # version of the package. | |

35 | # libgdbmg1-dev (development version of GNU libc 2-linked GDBM library) | |
