The problem is that my project actually uses a variable BLAS_LIBS and 
BLAS_LIB_PATH to know where and which blas is installed on the local 
machine. So the user needs to set these two variables in his 
user-config.jam like this:

<user-config.jam>
modules.poke : BLAS_LIBS : f77blas atlas ;
modules.poke : BLAS_LIB_PATH : /usr/local/lib ;
</user-config.jam>

And then in my project's Jamfile I use these variables like:

<Jamfile>
BLAS_LIBS = [ modules.peek : BLAS_LIBS ] ;
BLAS_LIB_PATH = [ modules.peek : BLAS_LIB_PATH ] ;

lib $(BLAS_LIBS) : : <search>$(BLAS_LIB_PATH) ;

project mine
: requirements
<library>/mine//$(BLAS_LIBS)
;
</Jamfile>

Now, generally the blas library is called 'libblas.a' but atlas for 
instance consists of multiple libraries. So I don't know in advance if 
there will be multiple or just one library ;0(
