    * "Error invoking target install of makefile /opt/oracle/product/9.0.1/plsql/lib/ins_plsql.mk"
      "Error invoking target install of makefile /opt/oracle/product/9.0.1/precomp/lib/ins-precomp.mk"
      "Error invoking target install of makefile /opt/oracle/product/9.0.1/precomp/lib/ins-net-client"

    I saw this error only when I installed Oracle 9i (9.0.1). People
    have sent me emails pointing out that the following solution also
    works for Mandrake 8.1, Mandrake 8.2, and for SuSE 8.0.

    Edit the file $ORACLE_HOME/bin/genclntsh and change the following line:

  LD_SELF_CONTAINED="-z defs"

    to read:

  LD_SELF_CONTAINED=""

    After that run the script $ORACLE_HOME/bin/genclntsh as the user
    "oracle" and not as the user "root". Also make sure you have all
    the Oracle environments set correctly!

$ su - oracle
$ $ORACLE_HOME/bin/genclntsh
Created /opt/oracle/product/9.0.1/lib/libclntst9.a
$

    After that hit Retry in the error dialog window. This always worked for me.

To remove this errors on 9i R1 database products, modify the following files by removing "-z defs":
$ORACLE_HOME/bin/genclntsh
$ORACLE_HOME/ldap/lib/ins_ldap.mk
$ORACLE_HOME/ldap/lib/env_ldap.mk
$ORACLE_HOME/sqlplus/lib/env_sqlplus.mk
similarly from 9i iAS find out makefiles who are using "-z defs" options. 
Remove "-z defs" option from all make files. Next time relink will not give any errors.
