I get the same thing with the native package.

I haven't gotten it to work using the rts-native, but I got my programs to
run with rts-fsu, apparently just fine.  Here's how to do it.  You need to
patch the s-osinte.ads file and rebuild the files just like you did to the
rts-native files.  Apply this patch.  (I installed gnat in /opt/gnat)

Then rebuild all the libs in rts-fsu/adalib with the following script:

#!/bin/tcsh -f
foreach f (../adainclude/*.ad[bs])
  gcc -c -O2 -gnatpga -I- $f

And remember to point your adainclude and adalib to rts-fsu/adainclude and
lib.

Sorry, no help here.
