Thanks for looking into this! I did the usual incantation perl Makefile.PL make make test
which gave the error in my previous message. Then I tried to go into the Real subdir and did perl Makefile.PL make sudo make install When I tried to use gsvdd as in the example, I get /usr/bin/perl: symbol lookup error: /usr/lib/atlas/liblapack.so.3gf: undefined symbol: _gfortran_pow_r8_i4 Thanks, Maggie On Thu, Sep 17, 2009 at 3:05 PM, Jan Hoogenraad <[email protected]>wrote: > I haven't had a problem with compilation.
