...mainly because it isn't something that DBI supports directly.
Your best bet is probably to go to the IIUG software archives
(hmm, how many times have I said this today? http://www.iiug.org)
and get hold of SQLCMD. In the code for the INFO statements
(sqlinfo.ec), you will find the statements I use to generate the
information loosely equivalent to "INFO INDEXES FOR sometable",
which is not a built-in command in SQL so you cannot run it
directly from DBD::Informix. Note that the statements assume
you know the table number (systables.tabid) entry for the table.
To deal with lists of tables, you will have to revise the code
