You are right.
It seem that environment variable GTAGSDBPATH isn't sent to gctags.
Gtags use putenv(3) or setenv(3) like this:

---------------------------------------------------------------------
Setting GTAGSDBPATH [gtags/gtags.c line 309]
---------------------------------------------------------------------
        /*
         * teach gctags(1) where is dbpath by environment variable.
         */
#ifdef HAVE_PUTENV
        {
                STRBUF *env = strbuf_open(0);

                strbuf_puts(env, "GTAGSDBPATH=");       ----------------+
                strbuf_puts(env, dbpath);                               |
                putenv(strbuf_value(env));                              |
                strbuf_close(env);                                      |
        }                                                               |
#else                                                                   |
        setenv("GTAGSDBPATH", dbpath, 1);               ----------------+
#endif /* HAVE_PUTENV */                                                |
                                                                        |

                 * gtags(1) set GTAGSDBPATH to the path GTAGS exist.    |
                 */                                                     |
                if (!(dbpath = getenv("GTAGSDBPATH")))  <---------------+
                        dbpath = ".";


How to communicate by environment variable in solaris?
