The current versions of LAPACK work differently on Windows and Linux.  I
also erroneously assumed a sort order on the returned eigenvalues, which
appears true for Linux and false for Windows.

I did post a followup on this, but it seems not to have made it to the
archives.

To calculate the principal eigenvalue you need:

require '~addons/lapack/lapack.ijs'
require '~addons/lapack/dgeev.ijs'
la=:3 : 0
'l c r'=.dgeev_jlapack_ y.
({. \: c){"1 r
)

With your example, this gives

     (%+/)la m2
0.0935079 0.152629 0.174427 0.166814 0.154946 0.257677
   (%+/)  power m2
0.0935079 0.152629 0.174427 0.166814 0.154946 0.257677

Please let me know if this works for you.
Best wishes,

John
