I recently added a shell script wrapper to compile/link FORTRAN 77 code
based on f2c, which for the purpose of Autoconf can be used as the
FORTRAN 77 compiler.  The configure script in subselect will need to be
modified to use R CMD config F77 (rather than grep/sed on etc/Makeconf)
for getting this.  But this will only make the configuration error go
away: the package will still not compile because the code, as wle and
princurve, use variable-sized arrays.

[I assume there are in your Atlas and cblas libs?  What does ldd on
Matrix.so say?]
