I have downloaded the pgapack_1.0.0.1.orig.tar.gz and pagpack_1.0.0.1-3.diff.gz files, unzipped the tar file and applied the patches. I configured with the following option:                 ./configure -arch linux -cc gcc -f77 g77 then I did a "make install", the build run OK. I "cd" to the test folder, run the "instverf" and the result showed that there were error in test 0 and test 4.           Test 0 had 994 errors.         Test 1 was successful.         Test 2 was successful.         Test 3 was successful.         Test 4 had 989 errors. Could you tell me what is wrong?  And how to correct the problem. My system is a Intel x86_64 base linux system. Enclosed are the build log, config.status, Makefile and instverf.data files.         Thanks. Puenlap Lee, Bull Information system, Inc.
