[완료]ABSOFT FORTRAN 95 설치시 에러

메뉴얼에 따라서
1. Installation.
2. Setting environment variables.
3. Optional packages.
4. Source code availability

1.To install Absoft Fortran 95, please run the installation script as
root, alternatively you can install as a normal user however this
configuration is not recommended. The installation script is located
in the same directory as this document, to run simply type:
./install
여기까지는 시리얼 넘버 넣어가면서 아무이상 없는데.

2.Before using this package, you need to create the ABSOFT environment variable
and add the directory containing the Fortran 95 tools to your PATH
environment variable. You should also add the appropriate set of commands
to your startup script to avoid having to do this step each time you want
to use the compilers.
If you are using bash, ksh, or sh, enter
ABSOFT=/opt/absoft10.1 (1)
PATH=$ABSOFT/bin:$PATH (2)
export ABSOFT PATH (3)
and add these commands to .bash_profile or .bashrc file in your home directory.

이 단계에서 겨우 .bashrc file찾아서(숨겨진 파일에 있더군요) (1)(2)(3)붙여넣어서 저장했습니다.
재부팅후 f95를 실행해 보니

abc@linux~> f95 plusa.f95
/opt/absoft10.1/bin/atmod: error while loading shared libraries: libstdc++.so.5:
cannot open shared object file: No such file or directory atmod failed.

이런 에러 메시지가 뜨네요. f tab tab 을 누르니 f90 f95 가 나오는 걸로 보아 설치는 된 거 같은데 PATH를 잘 못잡아준건가요? 갈켜주세요^^
