This is very strange. A couple of symlinks installed by the package in this directory are not removed. For some reason the `files.plist` is wrong, here's an excerpt:
```
       <dict>
            <key>file</key>
            <string>/usr/lib/sage-9.5.beta7/local/share/gap/bin/x86_64-pc-linux-gnu-default64-kv7/config.h</string>
            <key>mtime</key>
            <integer>1638070346</integer>
            <key>target</key>
            <string>/usr/lib/sage-9.5.beta7/local/share/gap/gen/config.h</string>
        </dict>
        <dict>
            <key>file</key>
            <string>/usr/lib/sage-9.5.beta7/local/share/gap/bin/x86_64-pc-linux-gnu-default64-kv7/gac</string>
            <key>mtime</key>
            <integer>1638070346</integer>
            <key>target</key>
            <string>al/bin/gac</string>
        </dict>
        <dict>
            <key>file</key>
            <string>/usr/lib/sage-9.5.beta7/local/share/gap/bin/x86_64-pc-linux-gnu-default64-kv7/gap</string>
            <key>mtime</key>
            <integer>1638070346</integer>
            <key>target</key>
            <string>al/bin/gap-bin</string>
        </dict>
        <dict>
            <key>file</key>
            <string>/usr/lib/sage-9.5.beta7/local/share/gap/bin/x86_64-pc-linux-gnu-default64-kv7/src</string>
            <key>mtime</key>
            <integer>1638070346</integer>
            <key>target</key>
            <string>/usr/lib/sage-9.5.beta7/local/share/gap/src</string>
        </dict>
```
These are the four symlinks installed in this directory, but two of them are incorrectly reported
Here are the relevant contents of the tarball:
```

```
Note that `../../src` and `../../gen/config.h` are ok (point to a directory and a file) while `../../gap` and `../../gac` point to other (absolute) symlinks. Is that the source of trouble? Maybe a bug in `xbps-create`?
