wrong message about non-existing file and strange file permissions in dataframe-0.9.1 package

[Sergei Steshenko]

Hello,

I've tried (for no good reason) to run a recently shown in this list example, 
and here's what I see:


"

octave:1> sys1=tf(1,[1 3 2])
error: no such file, 
`/mnt/sdb8/sergei/AFSWD_debug/20120424/octave-3.6.1/share/octave/packages/dataframe-0.9.1/@dataframe/size.m'
error: evaluating argument list element number 1

".

I.e., first of all, instead of "no such file" there should be "can not open 
file for reading".

Secondly, all but .m files of dataframe-0.9.1 have the correct permissions:

-rw-r--r-- 1 qemu users   306 2010-11-10 10:42 
dataframe/inst/@dataframe/isempty.m
-rw-r--r-- 1 qemu users   274 2010-12-13 11:40 dataframe/inst/@dataframe/ndims.m


has the correct permissions, all other .m files have the wrong "-rw-------" 
permissions.


Because of this problem dataframe-0.9.1 package is unusable when installed 
globally.

  Sergei.
