[Adding Server mods?Help please.]

I am having the same issue, but for 1.4.7. what does bukkit mean? the zip looks like any other of the mods ive added

[Custom NPCs mod]

after giving it a shot it just white screens forever. game works fine when i delete the zip from the mod folder. why is that?

[Custom NPCs mod]

I was looking into adding the Custom NPCs mod but in my research somebody said it wasnt bukkit compatable and wouldnt work with tekkit lite? can you add it to tekkit lite?

[adding mods]

So after a botched graphics mod install i went to make a clean install of minecraft and technic. to my suprise technic is no longer included as a modpack, so i will be playing tekkit lite now. the issue is how do i add millenaire to tekkit lite? i had added it to technic last week and was having a jolly good time.
