Yes, agreed.

Eli was wondering whether it was possible for library versions to be
checked.

One way is by looking at the corresponding #include file(s) that are
installed, along with the library, for the version number.

The #includes for the ungif library likely has version information
similar to the Gtk library; the file gtkfeatures.h has the following:

#define GTK_MAJOR_VERSION                               (1)
#define GTK_MINOR_VERSION                               (2)
#define GTK_MICRO_VERSION                               (8)
#define GTK_BINARY_AGE                                  (8)
#define GTK_INTERFACE_AGE                               (3)
#define GTK_CHECK_VERSION(major,minor,micro)    \
    (GTK_MAJOR_VERSION > (major) || \
     (GTK_MAJOR_VERSION == (major) && GTK_MINOR_VERSION > (minor)) || \
     (GTK_MAJOR_VERSION == (major) && GTK_MINOR_VERSION == (minor) && \
      GTK_MICRO_VERSION >= (micro)))
