building trouble

[marco perugini]

hi list,
we patched rlm_sqlippool to return more than the ip address; it's all ok 
while compiling but when we run radiusd-X we get this output:

rlm_passwd: nfields: 2 keyfield 0(DHCP-Client-Hardware-Address) listable: no
/etc/raddb/modules/dhcp_sqlippool[3]: Failed to link to module 
'rlm_sqlippool': /usr/lib64/freeradius/rlm_sqlippool.so: undefined 
symbol: sql_getvpdata
/etc/raddb/sites-enabled/dhcp[41]: Failed to find 
"dhcp_sqlippool.post-auth" in the "modules" section.
/etc/raddb/sites-enabled/dhcp[41]: Failed to parse 
"dhcp_sqlippool.post-auth" entry.
/etc/raddb/sites-enabled/dhcp[37]: Failed to parse "if" subsection.

can you help us on this?
thanks folks,
marco
