PROBLEM WITH THE COMPILER IN INSTALLATION OF NM7.2.0 ON A MAC OSX 10.7.3

Hi NMUSERS I´m trying to install NONMEM 7.2 on a Mac with OS 10.7.3 and I first installed gfortran 4.6.2 for Mac OS Lion (10.7) from the gfortran web site http://gcc.gnu.org/wiki/GFortranBinaries#MacOS After I tried to install NONMEM (installation from a directory) using a terminal window with the next command: /bin/bash/ SETUP72 /Users/Rod/desktop/cd_nonmem/NONMEM_7.2.0 /Applications/nm72 gfortran y /usr/bin/ar same rec i unzip nonmem72e.zip nonmem72r.zip and the complete messages that appear after enter this command are: SETUP72/Users/Rod/desktop/cd_nonmem/NONMEM_7.2.0 /Applications/nm72 gfortran y /usr/bin/ar same rec i unzip nonmem72e.zip nonmem72r.zip CD-ROM drive is /Users/Rod/desktop/cd_nonmem/NONMEM_7.2.0 NONMEM 7.2 directory is /Applications/nm72 Command for FORTRAN compiles is gfortran Optimization for Fortran compiles is y Command to build NONMEM archive is /usr/bin/ar Sizes is same (SIZES.f90 is always used) Recompile is rec All binaries will be recompiled Interactive is i Unzip program is unzip Encrypted source file is nonmem72e.zip Unencrypted file is nonmem72r.zip To learn how to override the defaults, enter %SETUP72 help Continue (y/n) [y]?y directory /Applications/nm72 Step 1a. Copy files from /Users/Rod/desktop/cd_nonmem/NONMEM_7.2.0 to /Applications/nm72 Step 1b. Copy files from /Users/Rod/desktop/cd_nonmem/NONMEM_7.2.0/NONMEM_7.2.0 to /Applications/nm72 Installing NONMEM 7.2.0 (Enter Ctrl-C to interrupt)... Dierectories already exist -skipping step 2a. Choosing platform-dependent files... os is Darwin cpu is i386 Will use install_Darwin Compiler is gfortran Will use existing finish === Checking compiler Version of gfortran is: GNU Fortran (GCC) 4.6.2 20111019 (prerelease) Copyright (C) 2011 Free Software Foundation, Inc.

For more information about these matters, see the file named COPYNG gfortran: error trying to exec 'as': execvp: No such file or directory Could not compile util/test.f90 ./util/dotest: line 72: gcc: command not found Could not assemble util/test.c with gcc Compiler gfortran and/or install program cannot be run Installation Aborted --So the error seems to be about gfortran as seen above in the last part. And I don´t know how to solve this problem, can anybody help me or tell me what I'm doing wrong? I thank in advance. PhD-st ORLANDO JACOBO E-mail: [email protected]; [email protected]
