It looks like it may have worked, but you should be careful to ensure that
if you do not have a .prj file (which defines the projection information
for the shape file) that you tell ogr2ogr what projection system the file
is actually in. In your case,  it looks like you did not need to tell
ogr2ogr what the projection system was (it guess for you) , but you cannot
always be sure with shape files what the projection system actually is
without a bit of prior knowledge of the nature of the file, or having its
metadata.

>From the ogr2ogr manual..


This option controls the output projection.

-t_srs srs_def:Reproject/transform to this SRS on output

This option controls the input spatial reference system, which ogr2ogr will
attempt to read from the .prj file if it is present.
If not, you may get an error like the one you say above.

-s_srs srs_def:Override source SRS

Regards,
Jason
