New ./configure error on Fedora 13 machine

[Dean S. Messing]

Was something in ./configure changed in the last month?

This:

  PATH=${PATH}:/usr/share/pvm3/lib ./configure LDFLAGS="-L/usr/lib64/atlas" 


has been working just fine for several months on my Fedora 13 system.

Today I down-loaded the source
from last night and tried to build. It died in the ./configure with:

  Generic Blas found
  checking if LAPACK is available... 
  checking for cheev_... no
  checking for cheev_ in -llapack... no
  checking for cheev_ in -llapack_rs6k... no
  configure: error: Impossible to find the LAPACK library.

The problem is this (from the config.log):

configure:22543: checking for cheev_ in -llapack
configure:22576: gcc -o conftest -g -O2 -D_LARGEFILE64_SOURCE  -DNDEBUG -fno-stack-protector -DNARROWPROTO -m64 -I$(top_srcdir)/modules/core/includes/ -I$(top_srcdir)/libs/MALLOC/includes/ -I$(top_srcdir)/modules/localization/includes/  -D_LARGEFILE64_SOURCE -DNDEBUG -fno-stack-protector -I$(top_srcdir)/modules/core/includes/ -I$(top_srcdir)/libs/MALLOC/includes/ -I$(top_srcdir)/modules/localization/includes/ -Wl,--no-as-needed conftest.c -llapack  -L/usr/lib/gcc/x86_64-redhat-linux/4.4.5 -L/usr/lib/gcc/x86_64-redhat-linux/4.4.5/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L/usr/lib/gcc/x86_64-redhat-linux/4.4.5/../../.. -lpthread -ldl -lcurses -lgfortranbegin -lgfortran -lm -lblas -lpthread -ldl -lcurses  -lm >&5
/usr/bin/ld: cannot find -llapack
collect2: ld returned 1 exit status


Here is the corresponding lines from my January 22nd build:

configure:22505: $? = 0
configure:22515: result: yes


The problem is that the -L/usr/lib64/atlas flags have vanished!
But it is in /usr/lib64/atlas that liblapack.so lives.

What's the fix?

Thanks
