as far as i understand /rstc/user1/erc/pushkar/ossim/src/packages/gdal is the 
build directory, not the installation one.
if so you have two alternatives:

good one, install gdal using ./configure --prefix=/my/inst/dir and then add 
-I/my/inst/dir/include -L/my/inst/dir/lib to the compile and link flags 
respectively.

hackish one, in order to find libgdal.a hidden by libtool you should add 
the .libs subdirectory to the library search path: 
-L/rstc/user1/erc/pushkar/ossim/src/packages/gdal/.libs
this is might be less portable, thou.
