There is a multitude of rc files that can be read on start-up of gschem 
or gsch2pcb. gafrc and gschrc can be definied on system, on user and on 
project level. My gafrc typically contains the following lines:

/----------gafrc-----
;(reset-component-library)   ; don't use system symbols
;(reset-source-library)     ; don't use system footprints

; Allow to source symbols from the current working directory
(define current-working-directory (getenv "PWD"))
(component-library current-working-directory)
(source-library  current-working-directory)

(source-library "/home/kmk/lilalaser/geda/kmk-pcb")

(component-library "/home/kmk/geda/kmk-sym")
(component-library "/home/kmk/geda/kmk-sym/analog")
(component-library "/home/kmk/geda/kmk-sym/digital")
(component-library "/home/kmk/geda/kmk-sym/connector")
(component-library "/home/kmk/geda/kmk-sym/analog/diode")
(component-library "/home/kmk/geda/kmk-sym/misc")
(component-library "/home/kmk/geda/kmk-sym/titleblock")
(component-library "/home/kmk/geda/kmk-sym/power")

This is already the case.

I don't quite get, what you mean by "current library".

This is how library search is done right now.
