Howto Simplify Multiple Exports in .bash_profile

Look more carefully at what you've written 
export CFLAGS="-I $HOME/.swish/include"; overwrites
export CFLAGS="-I $HOME/.gsl/include"; which overwrites
export CFLAGS="-I $HOME/.libstree/include";
and the LDFLAGS code is similar
LD_LIBRARY_PATH is different, each time you set it you are including its previous value, extending it rather than overwriting it:
export LD_LIBRARY_PATH=/home/ewijaya/MyBioTool/libstree-0.4.2/lib:${LD_LIBRARY_PATH}
To simplify, try something like:
export CFLAGS="-I $HOME/.swish/include:$HOME/.gsl/include:$HOME/.libstree/include";
hope this helps
export CFLAGS="-I $HOME/.swish/include"; overwrites
export CFLAGS="-I $HOME/.gsl/include"; which overwrites
export CFLAGS="-I $HOME/.libstree/include";
and the LDFLAGS code is similar
LD_LIBRARY_PATH is different, each time you set it you are including its previous value, extending it rather than overwriting it:

pvm_export
EXPORT(3PVM) EXPORT(3PVM) NAME
pvm_export, pvm_unexport - Mark environment variables to export through spawn SYNOPSIS
C int cc = pvm_export( char *name ) int cc = pvm_unexport( char *name ) Fortran Not available PARAMETERS
name Name of an environment variable to add to or delete from export list. DESCRIPTION
The routines pvm_export and pvm_unexport are provided for convenience in editing environment variable PVM_EXPORT, while maintaining the colon-separated list syntax it requires. The variable can be modified by other means, and at the same time by the pvm_export functions. pvm_export checks to see if a name is already in PVM_EXPORT before including it, and exporting a name more than once is not considered an error. Likewise, pvm_unexport will not complain if you specify a name not in PVM_EXPORT. EXAMPLES
C: /* PVM_EXPORT=SHELL:HOME */ pvm_export("DISPLAY"); pvm_export("TERM"); pvm_unexport("HOME"); /* PVM_EXPORT=SHELL:DISPLAY:TERM */ ERRORS
No error conditions are currently returned by pvm_export and pvm_unexport. SEE ALSO
